Gentoo Linux Security Advisory
Title: T1Lib: Buffer overflow (GLSA 200710-12)
Severity: normal
Exploitable: remote
Date: October 12, 2007
Bug(s): #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: media-libs/t1lib
Vulnerable: < 5.0.2-r1
Unaffected: >= 5.0.2-r1
Architectures: All supported architectures
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:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/t1lib-5.0.2-r1" |
