Local attackers can pass certain command line attempts to lpr running as root, fooling it to execute arbitrary commands as root. 2) The html2ps print filter, which is installed as part of the LPRng print system, allows remote attackers to execute arbitrary commands in the context of the lp user. Debian DSA-308-1 gzip - insecure temporary files (SGI BUG 892846) 1) A script included in the gzip package, creates its temporary files without taking precautions to avoid a symlink attack. 2) The gzexe script has a similar vulnerability which was patched in an earlier release but inadvertently reverted. LDS-PLaNET (SGI BUG 902169 & 902173) 1) A stack buffer overflow vulnerability that exists in an integral component of any modern Windows operating system, an RPC interface implementing Distributed Component Object Model Services (DCOM). NOTE: You can find more details about this vulnerability in the recent Microsoft Security Bulletin MS03-049 (CIAC Bulletin O-022). PLATFORM: - SGI IRIX systems - See SUSE Security Announcment ID: SUSE-SA:2002:40 lprng, html2ps for a complete listing of affected applications for SUSE. - Debian GNU/Linux 3.0 (woody) - Debian GNU/Linux 2.2 (potato) DAMAGE: - SUSE Security Announcement ID: SUSE-SA:2002:40 - these two issues combined allow attackers to mount a remote root attack. - Debian DSA-308-1: Creates its temporary files without taking precautions to avoid a symlink attack (CAN-2003-0367). - LDS-PLaNET: A remote attack resulting in execution of any commands on vulnerable Windows systems with SYSTEM privileges. SOLUTION: Install SGI's security patches 5473 and 5474. ______________________________________________________________________________ VULNERABILITY The risk is HIGH. A remote attacker can mount a remote root ASSESSMENT: attack. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/o-079.shtml ORIGINAL BULLETIN: ftp://patches.sgi.com/support/free/security/advisories /20040104-02-P.asc ADDITIONAL LINKS: http://www.suse.com/de/security/2002_040_lprng_html2ps.html http://www.lsd-pl.net/ http://www.debian.org/security/2003/dsa-308 CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2003-0367 ______________________________________________________________________________ [***** Start SGI Advisory 20040104-02-P *****] -----BEGIN PGP SIGNED MESSAGE----- SGI Security Advisory Title: userland binary vulnerabilities update Number: 20040104-02-P Date: February 5, 2004 Reference: SGI BUGS 902173, 902169, 892846, 876818 and 871671 Fixed in: Future release of IRIX and patch 5473 or 5474 ______________________________________________________________________________ SGI provides this information freely to the SGI user community for its consideration, interpretation, implementation and use. SGI recommends that this information be acted upon as soon as possible.

New patches 5473 and 5474 have been released to fix these issues. (SGI BUG 908652) - ----------------------- - --- Issue Specifics --- - ----------------------- It has been reported thru various channel that there are several vulnerabilities affecting applications on IRIX. * html2ps vulnerability (SGI BUG 871671) - http://www.suse.com/de/security/2002_040_lprng_html2ps.html * Safe.pm security hole (SGI BUG 876818) - http://use.perl.org/articles/02/10/06/1118222.shtml?tid=5 * gzexe and gznew predicatble tmp files (SGI BUG 892846) - http://www.debian.org/security/2003/dsa-308 * libdesktopicon.so buffer overflow (SGI BUG 902169) - http://www.lsd-pl.net/ * gr_osview buffer overflow (SGI BUG 902173) - http://www.lsd-pl.net/ SGI has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. This issue has been corrected in future releases of IRIX. - -------------- - --- Impact --- - -------------- To determine the version of IRIX you are running, execute the following command: # /bin/uname -R That will return a result similar to the following: # 6.5 6.5.21f The first number ("6.5") is the release name, the second ("6.5.21f" in this case) is the extended release name. The extended release name is the "version" we refer to throughout this document. - ---------------- - --- Solution --- - ---------------- SGI has provided a series of patches for these vulnerabilities. Our recommendation is to upgrade to IRIX 6.5.23, or install the appropriate patches. OS Version Vulnerable?
