Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor. Linux Kernel of (1) load_elf_library() function, (2) binfmt_aout() Functions include brk There is a flaw in the handling of the segment that causes a race condition.root You may get permission. Linux kernel is reported prone to a local privilege-escalation vulnerability. This issue arises in the 'uselib()' functions of the Linux binary-format loader as a result of a race condition. Successful exploitation of this vulnerability can allow a local attacker to gain elevated privileges on a vulnerable computer. The ELF and a.out loaders are reportedly affected by this vulnerability. The Linux kernel provides a binary format loader layer to load programs in different formats such as ELF or a.out or others, and the kernel also provides the sys_uselib() function to load corresponding binary programs. From the analysis of the uselib function of load_elf_library() in the binfmt_elf.c file, there is a problem in the processing of the BRK segment (VMA) of the library. This segment is established through current->mm->mmap_sem. When modifying the memory layout of the calling process\ '\' semaphore \'\' (semaphore) is not maintained, this can be used to mess with memory management and elevate privileges. Part of the source code fs/binfmt_elf.c is as follows: static int load_elf_library(struct file *file) { [904] down_write(¤t->mm->mmap_sem); error = do_mmap(file, ELF_PAGESTART(elf_phdata->p_vaddr), ( elf_phdata- > p_filesz + ELF_PAGEOFFSET(elf_phdata- > p_vaddr)), PROT_READ | PROT_WRITE | PROT_EXEC, MAP_FIXED | MAP_PRIVATE | MAP_DENYWRITE, (elf_phdata- > p_offset - ELF_PAGEOFFSET(elf_phdata- > p_vaddr))); >mmap_sem); if (error != ELF_PAGESTART(elf_phdata->p_vaddr)) goto out_free_ph;. ---------------------------------------------------------------------- Want to join the Secunia Security Team?

Spooler in Apache Foundation James 2.2.0 allows local users to cause a denial of service (memory consumption) by triggering various error conditions in the retrieve function, which prevents a lock from being released and causes a memory leak. James is prone to a memory leak denial of service vulnerability. This issue occurs during an error condition in the spooler. An attacker can exploit this issue by creating multiple error conditions and eventually consume system resources. Successful exploitation will ultimately crash the application denying service to legitimate users

Affected software: Kerio WinRoute Firewall (all versions) Kerio ServerFirewall (all versions) Kerio MailServer (all windows versions) Updates/Patches: Yes (see below) ______________________________________________________________________ General Information: 1. Executive summary: ------------------ As a result of its collaboration relationship the Secure Computer Group (SCG) along with dotpi.com Research Labs have determined the following security issue on some Kerio Software. Kerio WinRoute Firewall, Kerio ServerFirewall and Kerio MailServer are installed by default under 'Program Files' system folder. No change is done to the ACLs after the installation process. System administrators should enforce ACL security settings in order solve this problem. It is also highly recommended to verify this settings as part of the planning, installation, hardening and auditing processes. New versions of the software solve this an other minor problems so it is upgrade its highly recommended. 2. Technical details: ------------------ Following the latest trends and approaches to responsible disclosure, SCG and dotpi.com are going to withhold details of this flaw for three months. Full details will be published on 2005/03/14. This three month window will allow system administrators the time needed to obtain the patch before the details are released to the general public. 3. Risk Assessment factors: ------------------------ The attacker would need local interactive access to the installation directory. Remote access is also possible but default system settings do not make this easy. The most risky scenarios are the ones in which the server machine is shared among two or more users or those situations where Kerio service management have been delegated to a third party any other than local or domain system administrator. Special care should be taken on such environments and every step of the project: design, planning, deployment and management should consider this security issues. Privilege escalation, system and software tampering and the ability to alter service configuration are all real issues and all of them can be used as a second stage attack vector. 4. Solutions and recommendations: ------------------------------ Enforce the file system ACLs and/or upgrade to the latest versions: o Kerio Winroute Firewall 6.0.9 o Kerio ServerFirewall 1.0.1 o Kerio MailServer 6.0.5 As in any other case, follow, as much as possible, the Industry 'Best Practices' on Planning, Deployment and Operation on this kind of services. 5. Common Vulnerabilities and Exposures (CVE) project: --------------------------------------------------- The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2004-1023 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. ______________________________________________________________________ Acknowledgements: 1.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow. Apple Mac OS X Directory Service utilities use external programs insecurely, potentially allowing an attacker to execute arbitrary code. LibTIFF Library TIFFFetchStripThing() Perform memory allocation in functions CheckMalloc() An integer overflow vulnerability exists due to a flaw in the validation of the value passed to the function.LibTIFF Arbitrary code may be executed with the execution authority of the application that uses the library

Asante FM2008 running firmware 1.06 is shipped with a default username and password, which could allow remote attackers to gain unauthorized access. Asante FM2008 managed Ethernet switches contain a default backdoor account vulnerability. Note that these credentials aren't usable in the web administration interface, but only in the telnet or serial interfaces. Asante FM2008 v01.06 switches are vulnerable; other devices may be vulnerable as well

The configuration backup in Asante FM2008 running firmware 1.06 stores the username and password in cleartext, which could allow remote attackers to gain unauthorized access. FM2008 Managed Ethernet Switch is prone to a remote security vulnerability

Cisco Unity 2.x, 3.x, and 4.x, when integrated with Microsoft Exchange, has several hard coded usernames and passwords, which allows remote attackers to gain unauthorized access and change configuration settings or read outgoing or incoming e-mail messages. It is reported that vulnerable Unity systems contain default user accounts and passwords that can be used by an attacker to gain unauthorized access. This issue only arises when Unity is integrated with Microsoft Exchange. Unauthorized attakers may use these accounts to gain administrative access to vulnerable systems. Some accounts can allow attackers to disclose messages going to and from external voicemail systems. When used in conjunction with Exchange, there are multiple default username/password combinations. These default accounts are: EAdmin<systemid> UNITY_<servername> UAMIS_<servername> UOMNI_<servername> UVPIM_<servername> ESubsubscriber Accessible management interface with EAdmin <systemid> for application control. Any incoming or outgoing messages can be read using UNITY_<servername>, UAMIS_<servername>, UOMNI_<servername> or UVPIM_<servername>

Kerio Winroute Firewall before 6.0.7, ServerFirewall before 1.0.1, and MailServer before 6.0.5 use symmetric encryption for user passwords, which allows attackers to decrypt the user database and obtain the passwords by extracting the secret key from within the software. Kerio WinRoute Firewall, Kerio ServerFirewall, and Kerio MailServer are all reported prone to a design flaw. It is reported that these products store credentials in a local database store, these credentials are obscured using an unspecified symmetric encryption algorithm. Reports indicate that a universal secret key is employed to extract plain text from the credential hashes; this presents a security risk because the universal secret key is stored in the WinRoute Firewall, Kerio ServerFirewall, and Kerio MailServer binaries. Kerio is an Internet security software company whose main products include firewall and mail system. ______________________________________________________________________ Secure Computer Group - University of A Coruna http://research.tic.udc.es/scg/ -- x -- dotpi.com Information Technologies Research Labs http://www.dotpi.com ______________________________________________________________________ ID: #20041214-1 Document title: Insecure Credential Storage on Kerio Software Document revision: 1.0 Coordinated release date: 2004/12/14 Vendor Acknowledge date: 2004/10/06 Reported date: 2004/10/01 CVE Name: CAN-2004-1022 Other references: N/A ______________________________________________________________________ Summary: Impact: Insecure Credential Storage Rating/Severity: Medium Recommendation: Update to latest version Vendor: Kerio Technologies Inc. Affected software: Kerio WinRoute Firewall (all versions) Kerio ServerFirewall (all versions) Kerio MailServer (all versions) Updates/Patches: Yes (see below) ______________________________________________________________________ General Information: 1. Executive summary: ------------------ As a result of its collaboration relationship the Secure Computer Group (SCG) along with dotpi.com Research Labs have determined this security issue on Kerio WinRoute Firewall (KWF), Kerio ServerFirewall (KSF) and Kerio MailServer (KMS). Anyone with a cyphertext of this database (that is, with access to the configuration files) could reverse the encryption using a universal secret key hidden into the program logic. New versions of the software solve this and other minor problems so it is upgrade its highly recommended. 2. Technical details: ------------------ Following the latest trends and approaches to responsible disclosure, SCG and dotpi.com are going to withhold details of this flaw for three months. Full details will be published on 2005/03/14. This three month window will allow system administrators the time needed to obtain the patch before the details are released to the general public. 3. Risk Assessment factors: ------------------------ The attacker needs access to the user database, which is not normally a usual condition on a properly hardened firewall and/or mail server. Despite this, special care should be taken on shared environments where more than one technical staff work together on the firewall and/or the mail server. This kind of scenarios offer a potential opportunity for the insiders on the work of stealing identities and, therefore, breaking access control measures. It is also important to note that this could be an important second-stage resource for a successful attacker on an already compromised firewall and/or mail server. 4. Solutions and recommendations: ------------------------------ Upgrade to the latest versions: o Kerio Winroute Firewall 6.0.9 o Kerio ServerFirewall 1.0.1 o Kerio MailServer 6.0.5 As in any other case, follow, as much as possible, the Industry 'Best Practices' on Planning, Deployment and Operation on this kind of services. Note: Kerio Winroute Firewall 6.0.7 fixed CAN-2004-1022. Kerio Winroute Firewall 6.0.9 is the current version fixing CAN-2004-1022 and CAN-2004-1023 5. Common Vulnerabilities and Exposures (CVE) project: --------------------------------------------------- The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2004-1022 to this issue.
