Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200710-12 https://security.gentoo.org/
Severity: Normal Title: T1Lib: Buffer overflow Date: October 12, 2007 Bugs: #193437 ID: 200710-12
Synopsis ======= T1Lib is vulnerable to a buffer overflow allowing for the user-assisted execution of arbitrary code.
Background ========= T1Lib is a library for rasterizing bitmaps from Adobe Type 1 fonts.
Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/t1lib < 5.0.2-r1 >= 5.0.2-r1
========== Hamid Ebadi discovered a boundary error in the intT1_EnvGetCompletePath() function which can lead to a buffer overflow when processing an overly long filename.
Impact ===== A remote attacker could entice a user to open a font file with a specially crafted filename, possibly leading to the execution of arbitrary code with the privileges of the user running the application using T1Lib.
Workaround ========= There is no known workaround at this time.
Resolution ========= All T1Lib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/t1lib-5.0.2-r1"
References ========= [ 1 ] CVE-2007-4033 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4033
