Gentoo: 200805-13 Normal: PTeX Threat of Code Exec and File Overwrite

Multiple vulnerabilities were discovered in PTeX, possibly allowing the execution of arbitrary code or overwriting arbitrary files.. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 200805-13 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: PTeX: Multiple vulnerabilities Date: May 12, 2008 Bugs: #196673 ID: 200805-13 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======= Multiple vulnerabilities were discovered in PTeX, possibly allowing the execution of arbitrary code or overwriting arbitrary files. Background ========= PTeX is a TeX distribution with Japanese support. It is used for creating and manipulating LaTeX documents. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/ptex < 3.1.10_p20071203 > = 3.1.10_p20071203 Description ========== Multiple issues were found in the teTeX 2 codebase that PTeX builds upon (GLSA 200709-17, GLSA 200711-26). PTeX also includes vulnerable code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12, GLSA 200711-22) and from T1Lib (GLSA 200710-12). Impact ===== Remote attackers could possibly execute arbitrary code and local attackers could possibly overwrite arbitrary files with the privileges of the user running PTeX via multiple vectors, e.g. enticing users to open specially crafted files. Workaround ========= There is no known workaround at this time. Resolution ========= All PTeX users should upgrade to the latest version: # emerge--sync # emerge --ask --oneshot --verbose "> =app-text/ptex-3.1.10_p20071203" References ========= [ 1 ] GLSA 200708-05 https://security.gentoo.org/glsa/200708-05 [ 2 ] GLSA 200709-12 https://security.gentoo.org/glsa/200709-12 [ 3 ] GLSA 200709-17 https://security.gentoo.org/glsa/200709-17 [ 4 ] GLSA 200710-12 https://security.gentoo.org/glsa/200710-12 [ 5 ] GLSA 200711-22 https://security.gentoo.org/glsa/200711-22 [ 6 ] GLSA 200711-26 https://security.gentoo.org/glsa/200711-26 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200805-13 Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
