A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header. If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header. Affected products - ClamAV 0.96.4, Sophos 4.61.0 CVE no - CVE-2012-1458 41. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum.

The ELF file parser in eSafe 7.0.17.0, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified padding field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection. The following products are affected: eSafe Antivirus 7.0.17.0 Rising Antivirus 22.83.00.03 Panda Antivirus 10.0.2.7. Multiple file-parsing vulnerabilities leading to evasion in different antivirus(AV) products.

The ELF file parser in eSafe 7.0.17.0, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified abi field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection.

The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes. Affected products - Antiy-AVL 2.0.3.7, CAT-QuickHeal 11.00, Command 5.2.11.5, eSafe 7.0.17.0, F-Prot 4.6.2.117, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, VBA32 3.12.14.2 CVE no - CVE-2012-1460 43.

JP1/Cm2/Network Node Manager i (NNMi) contains vulnerabilities could allow a remote attacker to cause a denial of service (DoS) condition or execute arbitrary code. A remote attacker could cause a denial of service (DoS) condition or execute arbitrary code.

The Quantum Scalar i500 tape library with firmware before i7.0.3 (604G.GS00100), also distributed as the Dell ML6000 tape library with firmware before A20-00 (590G.GS00100) and the IBM TS3310 tape library with firmware before R6C (606G.GS001), uses default passwords for unspecified user accounts, which makes it easier for remote attackers to obtain access via unknown vectors. Cross scripting and preconfigured password vulnerabilities have been reported to exist in the Quantum Scalar i500, Dell ML6000 and IBM TS3310 tape libraries. The Quantum Scalar i500 and Dell ML6000 tape libraries contain the following WEB interface vulnerabilities: (1) The WEB interface allows unauthenticated remote users to view any file on the WEB server, such as http://device/logShow.htm?file=/etc/shadow . (2) http://device/checkQKMProg.htm There is a cross-site scripting vulnerability that allows you to get the session ID. (3) The POST parameter executes any command with the ROOT user. An information-disclosure vulnerability 2. A cross-site request-forgery vulnerability 4. A security-bypass vulnerability An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks. The information-disclosure vulnerability can allow the attacker to obtain sensitive information that may aid in launching further attacks. Exploiting the cross-site request-forgery may allow a remote attacker to perform certain administrative actions and gain unauthorized access to the affected application. Other attacks are also possible. Attackers can exploit a password weakness issue to bypass security restrictions to obtain sensitive information or perform unauthorized actions; this may aid in launching further attacks. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote attackers to cause a denial of service (daemon crash) via a Link State Update (aka LS Update) packet containing a network-LSA link-state advertisement for which the data-structure length is smaller than the value in the Length header field. Quagga, a routing software suite, contains multiple vulnerabilities that result in a denial-of-service condition. Quagga is prone to multiple remote security vulnerabilities including: 1. A denial-of-service vulnerability 2. Multiple buffer-overflow vulnerabilities An attackers can exploit these issues to execute arbitrary code in the context of the application or cause denial-of-service conditions. Quagga versions prior to 0.99.20.1 are vulnerable. ============================================================================ Ubuntu Security Notice USN-1441-1 May 15, 2012 quagga vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS Summary: Quagga could be made to crash if it received specially crafted network traffic.

Relevant releases/architectures: Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. The Quagga bgpd daemon implements the BGP (Border Gateway Protocol) routing protocol. The Quagga ospfd and ospf6d daemons implement the OSPF (Open Shortest Path First) routing protocol. A heap-based buffer overflow flaw was found in the way the bgpd daemon processed malformed Extended Communities path attributes. An attacker could send a specially-crafted BGP message, causing bgpd on a target system to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. The UPDATE message would have to arrive from an explicitly configured BGP peer, but could have originated elsewhere in the BGP network. (CVE-2011-3327) A stack-based buffer overflow flaw was found in the way the ospf6d daemon processed malformed Link State Update packets. An OSPF router could use this flaw to crash ospf6d on an adjacent router. (CVE-2011-3323) A flaw was found in the way the ospf6d daemon processed malformed link state advertisements. An OSPF neighbor could use this flaw to crash ospf6d on a target system. (CVE-2011-3324) A flaw was found in the way the ospfd daemon processed malformed Hello packets. An OSPF neighbor could use this flaw to crash ospfd on a target system. (CVE-2011-3325) A flaw was found in the way the ospfd daemon processed malformed link state advertisements. An OSPF router in the autonomous system could use this flaw to crash ospfd on a target system. (CVE-2011-3326) An assertion failure was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to cause ospfd on an adjacent router to abort. (CVE-2012-0249) A buffer overflow flaw was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to crash ospfd on an adjacent router. (CVE-2012-0250) Two flaws were found in the way the bgpd daemon processed certain BGP OPEN messages. A configured BGP peer could cause bgpd on a target system to abort via a specially-crafted BGP OPEN message.

The Linux kernel before 3.3.1, when KVM is used, allows guest OS users to cause a denial of service (host OS crash) by leveraging administrative access to the guest OS, related to the pmd_none_or_clear_bad function and page faults for huge pages. Cross scripting and preconfigured password vulnerabilities have been reported to exist in the Quantum Scalar i500, Dell ML6000 and IBM TS3310 tape libraries. The Linux kernel is prone to a local denial-of-service vulnerability. Attackers can exploit this issue to cause the kernel to crash, denying service to legitimate users. Linux Kernel 2.6.x is vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2012:0743-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0743.html Issue date: 2012-06-18 CVE Names: CVE-2012-0044 CVE-2012-1179 CVE-2012-2119 CVE-2012-2121 CVE-2012-2123 CVE-2012-2136 CVE-2012-2137 CVE-2012-2372 CVE-2012-2373 ===================================================================== 1. Summary: Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. This update fixes the following security issues: * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM (Kernel-based Virtual Machine) environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled (it is not enabled by default), and that also have macvtap configured for at least one guest. (CVE-2012-2119, Important) * When a set user ID (setuid) application is executed, certain personality flags for controlling the application's behavior are cleared (that is, a privileged application will not be affected by those flags). It was found that those flags were not cleared if the application was made privileged via file system capabilities. A local, unprivileged user could use this flaw to change the behavior of such applications, allowing them to bypass intended restrictions. Note that for default installations, no application shipped by Red Hat for Red Hat Enterprise Linux is made privileged via file system capabilities. (CVE-2012-2123, Important) * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A privileged guest user in a KVM guest could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-2136, Important) * A buffer overflow flaw was found in the setup_routing_entry() function in the KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts (MSI) routing entry was handled. A local, unprivileged user could use this flaw to cause a denial of service or, possibly, escalate their privileges. (CVE-2012-2137, Important) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_none_or_clear_bad(), when called with mmap_sem in read mode, and Transparent Huge Pages (THP) page faults interacted. A privileged user in a KVM guest with the ballooning functionality enabled could potentially use this flaw to crash the host. A local, unprivileged user could use this flaw to crash the system. (CVE-2012-1179, Moderate) * A flaw was found in the way device memory was handled during guest device removal. Upon successful device removal, memory used by the device was not properly unmapped from the corresponding IOMMU or properly released from the kernel, leading to a memory leak. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2012-2121, Moderate) * A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_populate() and pte_offset_map_lock() interacted on 32-bit x86 systems with more than 4GB of RAM. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2373, Moderate) Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5.

ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/nginx < 1.0.14 >= 1.0.14 Description =========== Multiple vulnerabilities have been found in nginx: * The TLS protocol does not properly handle session renegotiation requests (CVE-2009-3555). * The "ngx_http_process_request_headers()" function in ngx_http_parse.c could cause a NULL pointer dereference (CVE-2009-3896). * nginx does not properly sanitize user input for the the WebDAV COPY or MOVE methods (CVE-2009-3898). * The "ngx_resolver_copy()" function in ngx_resolver.c contains a boundary error which could cause a heap-based buffer overflow (CVE-2011-4315). * nginx does not properly parse HTTP header responses which could expose sensitive information (CVE-2012-1180). Impact ====== A remote attacker could possibly execute arbitrary code with the privileges of the nginx process, cause a Denial of Service condition, create or overwrite arbitrary files, or obtain sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All nginx users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14" References ========== [ 1 ] CVE-2009-3555 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3555 [ 2 ] CVE-2009-3896 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3896 [ 3 ] CVE-2009-3898 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3898 [ 4 ] CVE-2011-4315 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4315 [ 5 ] CVE-2012-1180 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1180 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201203-22.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

McAfee Email and Web Security (EWS) 5.x before 5.5 Patch 6 and 5.6 before Patch 3, and McAfee Email Gateway (MEG) 7.0 before Patch 1, allows remote authenticated users to reset the passwords of arbitrary administrative accounts via unspecified vectors. A remote attacker could leverage the cross-site scripting issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Exploiting the information-disclosure issues allow the attacker to view local files within the context of the Web server process. Exploiting the security-bypass vulnerability allows attackers to bypass security restrictions and obtain sensitive information or perform unauthorized actions. Exploiting the directory-traversal issue allows attackers to use directory-traversal strings to retrieve arbitrary files in the context of the affected application. Exploiting the insecure-encryption issue allows attackers to determine encryption keys, which may lead to further attacks. The solution offers incoming threat protection, outgoing encryption, data loss prevention, and more. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!
