Gentoo Linux Security Advisory
Title: FontForge: User-assisted execution of arbitrary code (GLSA 201201-08)
Severity: normal
Exploitable: remote
Date: January 23, 2012
Bug(s): #386293
ID: 201201-08
Synopsis
A stack-based buffer overflow flaw in FontForge could result in
execution of arbitrary code or a Denial of Service.
Background
FontForge is a PostScript font editor and converter.
Affected Packages
Package: media-gfx/fontforge
Vulnerable: < 20110222-r1
Unaffected: >= 20110222-r1
Architectures: All supported architectures
Description
FontForge is vulnerable to an error when processing the
"CHARSET_REGISTRY" header in font files, which could cause a stack-based
buffer overflow.
Impact
A remote attacker could entice a user to open a specially crafted BDF
file using FontForge font editor, possibly resulting in the remote
execution of arbitrary code with the privileges of the FontForge process,
or a Denial of Service (application crash).
Workaround
There is no known workaround at this time.
Resolution
All FontForge users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/fontforge-20110222-r1"
| NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 12, 2011. It is likely that your system is
already no longer affected by this issue.
