IBM AIX 5.2

Buffer overflow in invscout in IBM AIX 5.1.0 through 5.3.0 might allow local users to execute arbitrary code via a long command line argument.

Buffer overflow in bos.rte.libc in IBM AIX 5.2 and 5.3 allows local users to execute arbitrary code via the "r-commands", possibly including (1) rdist, (2) rsh, (3) rcp, (4) rsync, and (5) rlogin.

Buffer overflow in errpt in IBM AIX 5.2, 5.3, and 6.1 allows local users to gain privileges via unknown attack vectors.

Buffer overflow in the arp command of IBM AIX 5.3 L, 5.3, 5.2.2, 5.2 L, and 5.2 allows local users to cause a denial of service (crash) via a long iftype argument.

lscfg in IBM AIX 5.2 and 5.3 allows local users to modify arbitrary files via a symlink attack.

rm_mlcache_file in bos.rte.install in AIX 5.1.0 through 5.3.0 allows local users to overwrite arbitrary files via a symlink attack on temporary files.

Buffer overflow in the PerlIO implementation in Perl 5.8.0, when installed with setuid support (sperl), allows local users to execute arbitrary code by setting the PERLIO_DEBUG variable and executing a Perl script whose full pathname contains a long directory tree.

ftpd in IBM AIX 5.1, 5.2 and 5.3 allows remote authenticated users to cause a denial of service (port exhaustion and memory consumption) by using all ephemeral ports.

RC.BOOT in IBM AIX 5.1, 5.2, and 5.3 does not "use a secure location for temporary files," which allows local users to have an unknown impact, probably by overwriting files.

lspath in AIX 5.2, 5.3, and possibly earlier versions, does not drop privileges before processing the -f option, which allows local users to read one line of arbitrary files.

The ctstrtcasd program in RSCT 2.3.0.0 and earlier on IBM AIX 5.2 and 5.3 does not properly drop privileges before executing the -f option, which allows local users to modify or create arbitrary files.

LSCFG in IBM AIX 5.2 and 5.3 does not create temporary files securely, which allows local users to corrupt /etc/passwd and possibly other system files via the trace file.
