Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFSSETPKGEXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable.

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFSGETBOOTINFO fcntl calls.

Unspecified vulnerability in CarbonCore in Apple Mac OS X 10.4.11 and 10.5.6 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via a crafted resource fork that triggers memory corruption.

Remote Apple Events in Apple Mac OS X 10.4.11 and 10.5.6 allows remote attackers to cause a denial of service (application termination) or obtain sensitive information via unspecified vectors that trigger an out-of-bounds memory access.

csregprinter in the Printing component in Apple Mac OS X 10.4.11 and 10.5.6 does not properly handle error conditions, which allows local users to execute arbitrary code via unknown vectors that trigger a heap-based buffer overflow.

The Remote Apple Events server in Apple Mac OS X 10.4.11 and 10.5.6 does not properly initialize a buffer, which allows remote attackers to read portions of memory.

Certificate Assistant in Apple Mac OS X 10.5.6 allows local users to overwrite arbitrary files via unknown vectors related to an "insecure file operation" on a temporary file.

Unknown vulnerability in QuickTime Java in Mac OS X v10.3 and Mac OS X Server 10.3 allows attackers to gain "unauthorized access to a system."

A "potential buffer overflow in ruleset parsing" for Sendmail 8.12.9, when using the nonstandard rulesets (1) recipient (2), final, or (3) mailer-specific envelope recipients, has unknown consequences.

DirectoryServices in MacOS X trusts the PATH environment variable to locate and execute the touch command, which allows local users to execute arbitrary commands by modifying the PATH to point to a directory containing a malicious touch program.

Apple File Protocol (AFP) in Mac OS X before 10.2.4 allows administrators to log in as other users by using the administrator password.

Event Monitor in Apple Mac OS X before 10.6.3 does not properly validate hostnames of SSH clients, which allows remote attackers to cause a denial of service (arbitrary client blacklisting) via a crafted DNS PTR record, related to a "plist injection issue."

Directory traversal vulnerability in AFP Server in Apple Mac OS X before 10.6.3 allows remote attackers to list a share root's parent directory, and read and modify files in that directory, via unspecified vectors.

SFLServer in OS Services in Apple Mac OS X before 10.6.3 allows local users to gain privileges via vectors related to use of wheel group membership during access to the home directories of user accounts.

Directory Services in Apple Mac OS X before 10.6.3 does not properly perform authorization during processing of record names, which allows local users to gain privileges via unspecified vectors.

The default configuration of the FreeRADIUS server in Apple Mac OS X Server before 10.6.3 permits EAP-TLS authenticated connections on the basis of an arbitrary client certificate, which allows remote attackers to obtain network connectivity via a crafted RADIUS Access Request message.

Multiple stack-based buffer overflows in iChat Server in Apple Mac OS X Server before 10.6.3 allow remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.

AFP Server in Apple Mac OS X before 10.6.3 does not prevent guest use of AFP shares when guest access is disabled, which allows remote attackers to bypass intended access restrictions via a mount request.

Description of problem: CVE-2009-3553 (bug #530111) has not been completely fixed.

Version-Release number of selected component (if applicable): Versions known to be affected:

cups-1.3.7-11.el54.5 (RHEL-5.4.z) cups-1.3.7-16.el5 (RHEL-5)

Additional info: The cause is that the cupsdDoSelect() function uses one of several implementations depending on the underlying select/poll capabilities of the operating system. For kqueue and epoll implementations, cupsdRemoveSelect() does not immediately decrease the reference count for the file descriptor and instead adds it to the cupsdinactivefds array. File descriptors in that array are finally dereferenced in cupsdStopSelect() (i.e. program termination).

In Red Hat Enterprise Linux, the epoll implementation is used.

The previous fix for CVE-2009-3553 was to check that another reference was held for the file descriptor before calling the writecb function; however, that will always be the case for both the epoll and kqueue implementations.

The correct fix is to check whether the file descriptor is in the cupsdinactivefds array before calling the writecb function.

OpenSSH 4.4 was released and mentions:

Fix an unsafe signal hander reported by Mark Dowd. The signal handler was vulnerable to a race condition that could be exploited to perform a pre-authentication denial of service. On portable OpenSSH, this vulnerability could theoretically lead to pre-authentication remote code execution if GSSAPI authentication is enabled, but the likelihood of successful exploitation appears remote.

This could only affect RHEL4 as previous RHEL did not support GSSAPI

jabberd2 before 2.2.14 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.

The dochangecipherspec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

The System Profiler in Mac OS X 10.4.2 labels a Bluetooth device with "Requires Authentication: No" even when the user has selected the "Require pairing for security" option, which could confuse users about which setting is valid.

AFP Server on Mac OS X 10.3.x to 10.3.5, when a guest has mounted an AFP volume, allows the guest to "terminate authenticated user mounts" via modified SessionDestroy packets.

Buffer overflow in Directory Services in Mac OS X 10.3.9 and 10.4.2 allows remote attackers to execute arbitrary code during authentication.

Authorization Services in securityd for Apple Mac OS X 10.3.9 allows local users to gain privileges by granting themselves certain rights that should be restricted to administrators.

AirPort in Apple Mac OS X 10.5.8 allows remote attackers to cause a denial of service (out-of-bounds read and reboot) via Wi-Fi frames on the local wireless network.

Apple Type Services (ATS) in Apple Mac OS X before 10.7.3 does not properly manage memory for data-font files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted font that is accessed by Font Book.

Buffer overflow in cd9660.util in Apple Mac OS X 10.0 through 10.3.2 and Apple Mac OS X Server 10.0 through 10.3.2 may allow local users to execute arbitrary code via a long command line parameter.
