Format string vulnerability in the _msgout function in rpc.pcnfsd in IBM AIX 6.1, 5.3, and earlier; IBM VIOS 2.1, 1.5, and earlier; NFS/ONCplus B.11.31_09 and earlier on HP HP-UX B.11.11, B.11.23, and B.11.31; and SGI IRIX 6.5 allows remote attackers to execute arbitrary code via an RPC request containing format string specifiers in an invalid directory name.

Unknown vulnerability in the login program on AIX before 4.0 could allow remote users to specify 100 or more environment variables when logging on, which exceeds the length of a certain string, possibly triggering a buffer overflow.

Unknown vulnerability in AIX before 4.0 with unknown attack vectors and unknown impact, aka "security issue," as fixed by APAR IY28225.

Some functions that implement the locale subsystem on Unix do not properly cleanse user-injected format strings, which allows local attackers to execute arbitrary commands via functions such as gettext and catopen.

Vulnerability in AIX 3.2.x and 4.x allows local users to gain write access to files on locally or remotely mounted AIX filesystems.

Buffer overflow in Source Code Browser Program Database Name Server Daemon (pdnsd) for the IBM AIX C Set ++ compiler.

Vulnerability in ptrace in AIX 4.3 allows local users to gain privileges by attaching to a setgid program.

snap command in AIX before 4.3.2 creates the /tmp/ibmsupt directory with world-readable permissions and does not remove or clear the directory when snap -a is executed, which could allow local users to access the shadowed password file by creating /tmp/ibmsupt/general/passwd before root runs snap -a.

ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service.

The AIX FTP client can be forced to execute commands from a malicious server through shell metacharacters (e.g. a pipe character).
