Red Hat Security Advisory 2017-1262-01 - The rpcbind utility is a server that converts Remote Procedure Call program numbers into universal addresses. It must be running on the host to be able to make RPC calls on a server on that machine. Security Fix: It was found that due to the way rpcbind uses libtirpc, a memory leak can occur when parsing specially crafted XDR messages. An attacker sending thousands of messages to rpcbind could cause its memory usage to grow without bound, eventually causing it to be terminated by the OOM killer.

SGI Security Advisory 20040507-01-P - Adam Gowdiak from the Poznan Supercomputing and Networking Center has reported that under certain conditions the /usr/sbin/cpr binary can be forced to load a user provided library while restarting the checkpointed process which can then be used to obtain root user privileges. All versions of IRIX prior to 6.5.25 are affected.

SGI Security Advisory 20040601-01-P - Adam Gowdiak from the Poznan Supercomputing and Networking Center has reported that under certain conditions non privileged users can use the syssgi system call SGI_IOPROBE to read and write kernel memory which can be used to obtain root user privileges. Patches have been released for this and other issues. At this time, IRIX versions 6.5.20 to 6.5.24 are considered susceptible.

NetBSD Security Advisory 2004-010 - Some of the functions in /usr/src/sys/compat/ which implement execution of foreign binaries (such as Linux, FreeBSD, IRIX, OSF1, SVR4, HPUX, and ULTRIX) use argument data in unsafe ways prior to calling the kernel syscall.

iDEFENSE Security Advisory 01.13.05-3 - Local exploitation of a design error vulnerability in the inpview command included in multiple versions of Silicon Graphics Inc.'s IRIX could allow for arbitrary code execution as the root user. iDEFENSE has confirmed the existence of this vulnerability in SGI IRIX version 6.5.9 (feature) and 6.5.22 (maintenance).

iDEFENSE Security Advisory 04.07.05 - Local exploitation of an information disclosure vulnerability in the gr_osview command included in multiple versions of Silicon Graphics Inc.'s IRIX Operating System could allow for the disclosure of sensitive information such as the root user's password hash. The vulnerability specifically exists in the way that gr_osview opens user-specified description files without dropping privileges. When this is combined with the debug option, it is possible to dump a line from an arbitrary file, regardless of its protection.

The vulnerability specifically exists in the way that gr_osview opens user specified files without dropping privileges. When a file is specified using the -s option, it will be opened regardless of permissions, and operating system usage information will be written into it.

Secunia Security Advisory - A security issue has been reported in SGI IRIX, which potentially can be exploited by malicious users to disclose and modify sensitive information.

Secunia Security Advisory - SGI has acknowledged a vulnerability in IRIX, which can be exploited by malicious people to compromise a vulnerable system.

iDEFENSE Security Advisory 10.10.05-1 - Local exploitation of a design error vulnerability in the runpriv command included in multiple versions of Silicon Graphics Inc.'s IRIX could allow for arbitrary code execution as the root user. iDEFENSE has confirmed the existence of this vulnerability in SGI IRIX version 6.5.22 (maintenance). It is suspected that previous and later versions of both the feature and maintenance revisions of IRIX 6.5 are also vulnerable.

IRIX suffers from local kernel memory disclosure and denial of service vulnerabilities.

Secunia Security Advisory - A vulnerability has been reported in SGI IRIX, which can be exploited by malicious, local users to disclose potentially sensitive information and cause a DoS (Denial of Service).

CA Technologies support is alerting customers about a medium risk vulnerability that may allow a local attacker to gain additional privileges with products using CA Common Services running on the AIX, HP-UX, Linux, and Solaris platforms. The vulnerability, CVE-2016-9795, occurs due to insufficient validation by the casrvc program. A local unprivileged user can exploit the vulnerability to modify arbitrary files, which can potentially allow a local attacker to gain root level access.

Xorg X11 server on AIX local privilege escalation exploit.

This Metasploit module has been tested with AIX 7.1 and 7.2, and should also work with 6.1. Due to permission restrictions of the crontab in AIX, this module does not use cron, and instead overwrites /etc/passwd in order to create a new user with root privileges. All currently logged in users need to be included when /etc/passwd is overwritten, else AIX will throw 'Cannot get "LOGNAME" variable' when attempting to change user. The Xorg '-fp' parameter used in the OpenBSD exploit does not work on AIX, and is replaced by '-config', in conjuction with ANSI-C quotes to inject newlines when overwriting /etc/passwd.
