|Gentoo Linux Security Advisory
Title: T1Lib: Buffer overflow (GLSA 200710-12)
Date: October 12, 2007
T1Lib is vulnerable to a buffer overflow allowing for the user-assisted execution of arbitrary code.
T1Lib is a library for rasterizing bitmaps from Adobe Type 1 fonts.
Vulnerable: < 5.0.2-r1
Unaffected: >= 5.0.2-r1
Architectures: All supported architectures
Hamid Ebadi discovered a boundary error in the intT1_EnvGetCompletePath() function which can lead to a buffer overflow when processing an overly long filename.
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.
There is no known workaround at this time.
All T1Lib users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/t1lib-5.0.2-r1"
