IBM AIX 3.2.5

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.

Some implementations of rlogin allow root access if given a -froot parameter.

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.

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

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.

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

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.

Local user gains root privileges via buffer overflow in rdist, via expstr() function.

Buffer overflow in NLS (Natural Language Service).

Buffer overflow in ping in AIX 4.2 and earlier allows local users to gain root privileges via a long command line argument.

Buffer overflow in AIX lquerylv program gives root access to local users.

The suidperl and sperl program do not give up root privileges when changing UIDs back to the original users, allowing root access.

AIX bugfiler program allows local users to gain root access.

AIX Licensed Program Product performance tools allow local users to gain root access.

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

Denial of service when an attacker sends many SYN packets to create multiple connections without ever sending an ACK to complete the connection, aka SYN flood.

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.

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