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
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"
