Unspecified vulnerability in ImageIO in Apple Mac OS X 10.3.9 and 10.4 through 10.4.8 allows remote user-assisted attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted RAW image that triggers memory corruption. A vulnerabilty in the Apple Mac OS X DirectoryService may allow unprivileged users to change the root password. Apple ColorSync contains a buffer overflow vulnerability that may allow an attacker to execute arbitrary code. Mac OS X is prone to multiple vulnerabilities including stack-based buffer-overflow issues, denial-of-service vulnerabilities, two memory-corruption issues, an integer-overflow issue, two authentication-bypass issues, an information-disclosure vulnerability, and an insecure command-execution issue. An attacker can exploit these issues to execute arbitrary code in the context of the user running the application, cause denial-of-service conditions, compromise the application, and access or modify data. Few details regarding these issues are currently available. Separate BIDs for each issue will be created as new information becomes available. Mac OS X and Mac OS X Server versions 10.3.9 and 10.4 through 10.4.8 are vulnerable. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The Bonjour functionality in iChat in Apple Mac OS X 10.3.9 allows remote attackers to cause a denial of service (persistent application crash) via unspecified vectors, possibly related to CVE-2007-0614. Apple iChat is prone to multiple remote denial-of-service vulnerabilities. These issues affect the Bonjour functionality. Apple iChat 3.1.6 is reported affected; other versions may be vulnerable as well. Apple iChat is a video chat tool bundled with Apple's family of operating systems. Several denial-of-service vulnerabilities exist in iChat's Bonjour feature, which allows automatic discovery of computers. There are no restrictions on finding available contacts via mDNS queries, iChat will add the broadcasted _presence._tcp record even if the contact does not exist, so a malicious user can broadcast a fake record so that iChat users using Bonjour cannot discover more peers, unable to communicate reliably. Trying to start iChat Bonjour again will fail because mDNSResponder keeps a specially crafted record. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The CFUserNotificationSendRequest function in UserNotificationCenter.app in Apple Mac OS X 10.4.8, when used in combination with diskutil, allows local users to gain privileges via a malicious InputManager in Library/InputManagers in a user's home directory, which is executed when Cocoa applications attempt to notify the user. Apple's UserNotificationCenter contains a vulnerability that may allow local users to gain elevated privileges. According to Apple's information, gaining elevated privileges could result in unauthorized overwriting or modification of system files. This issue stems from a flaw in the UserNotificationCenter application that results in arbitrary code-execution with wheel-group privileges. This issue affects Apple Mac OS X version 10.4.8; other versions may also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

Format string vulnerability in Apple iChat 3.1.6 allows remote attackers to cause a denial of service (null pointer dereference and application crash) and possibly execute arbitrary code via format string specifiers in an aim:// URI. Apple iChat contains a format string vulnerability. This vulnerability may allow a remote, unauthenticated attacker to execute arbitary code. A vulnerability in the way Apple Mac OS X handles corrupted Universal Mach-O Binaries may result in execution of arbitrary code or denial of service. Apple iChat is prone to a remote format-string vulnerability because the application fails to properly sanitize user-supplied input before including it in the format-specifier argument of a formatted-printing function.

crashdump in Apple Mac OS X 10.4.8 allows local users in the admin group to modify arbitrary files or gain privileges via a symlink attack on application logs in /Library/Logs/CrashReporter/. CrashReporter contains a privilege escalation vulnerability that may allow authenticated users to run commands as root. In order to exploit this vulnerability, — Must belong to the management group of Cull. Mac OS X is prone to a denial-of-service vulnerability. Local attackers may use this vulnerability to elevate their privileges. If an anomaly is detected, a crashdump is launched to investigate the cause of the crash and report it to the user. When reporting an exception, crashdump will first try to write the report to the user's home directory (/Users/[user]/Library/Logs/CrashReporter/), and if the home directory is unavailable due to permissions, etc., it will try to use the system A scoped log directory, such as /Library/Logs/CrashReporter/. But crashdump follows symlinks and users in the administrators group have write access to the directory. Since crashreporterd runs with root privileges, an attacker can embed a symbolic link in the /Library/Logs/CrashReporter/ directory to modify arbitrary files. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The Bonjour functionality in mDNSResponder, iChat 3.1.6, and InstantMessage framework 428 in Apple Mac OS X 10.4.8 allows remote attackers to cause a denial of service (persistent application crash) via a crafted phsh hash attribute in a TXT key. A vulnerability in the way Apple Mac OS X handles corrupted Universal Mach-O Binaries may result in execution of arbitrary code or denial of service. According to Apple information, iChat of Bonjour In message processing NULL Pointer Dereferencing causes the application to crash.Third parties on the local network can cause the application to crash. Apple iChat is prone to multiple remote denial-of-service vulnerabilities. These issues affect the Bonjour functionality. Apple iChat 3.1.6 is reported affected; other versions may be vulnerable as well. Apple iChat is a video chat tool bundled with Apple's family of operating systems. Several denial-of-service vulnerabilities exist in iChat's Bonjour feature, which allows automatic discovery of computers. There are no restrictions on finding available contacts via mDNS queries, iChat will add the broadcasted _presence._tcp record even if the contact does not exist, so a malicious user can broadcast a fake record so that iChat users using Bonjour cannot discover more peers, unable to communicate reliably. In addition, the iChat agent may have an exception when processing a specially crafted TXT key hash, resulting in a crash when sending a SIGTRAP signal to the process. Trying to start iChat Bonjour again will fail because mDNSResponder keeps a specially crafted record. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.
