Trusted Execution in IBM AIX 6.1 uses an incorrect pathname argument in a call to the trustchk_block_write function, which might allow local users to modify trusted files, related to missing checks in the TSD_FILES_LOCK policy for modifications performed via hard links, a different vulnerability than CVE-2007-6680.

The proc filesystem in the kernel in IBM AIX 5.2 and 5.3 does not properly enforce directory permissions when a file executing from a directory has weaker permissions than the directory itself, which allows local users to obtain sensitive information.

The checkpoint and restart feature in the kernel in IBM AIX 5.2, 5.3, and 6.1 does not properly protect kernel memory, which allows local users to read and modify portions of memory and gain privileges via unspecified vectors involving a restart of a 64-bit process, probably related to the as_getadsp64 function.

MQSeries 5.1 in IBM WebSphere MQ 5.1 through 5.3.1 on the HP NonStop and Tandem NSK platforms does not require mqm group membership for execution of administrative tasks, which allows local users to bypass intended access restrictions via the runmqsc program, related to “Pathway panels.”
