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 Description =========== 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 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200710-12.xml 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.
