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.

The kernel in IBM AIX 5.2 and 5.3 does not properly handle resizing JFS2 filesystems on concurrent volume groups spread across multiple nodes, which allows local users of one node to cause a denial of service (remote node crash) by using chfs or lreducelv to reduce a filesystem's size.

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.

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 WPAR system call implementation in the kernel in IBM AIX 6.1 allows local users to cause a denial of service via unknown calls that trigger "undefined behavior."

The kernel in IBM AIX 6.1 allows local users with ProbeVue privileges to read arbitrary kernel memory and obtain sensitive information via unspecified vectors.

The nddstat programs on IBM AIX 5.2, 5.3, and 6.1 do not properly handle environment variables, which allows local users to gain privileges by invoking (1) atmstat, (2) entstat, (3) fddistat, (4) hdlcstat, or (5) tokstat.

The lsmcode program on IBM AIX 5.2, 5.3, and 6.1 does not properly handle environment variables, which allows local users to gain privileges, a different vulnerability than CVE-2004-1329.

The ps program in bos.rte.control in IBM AIX 5.2, 5.3, and 6.1 allows local users to obtain sensitive information via unspecified vectors.

Buffer overflow in the pioout program in printers.rte in IBM AIX 5.2, 5.3, and 6.1 allows local users to gain privileges via a long command line option.

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 an error in the support for links in the TSD_FILES_LOCK policy.
