A stack-based buffer overflow flaw in FontForge could result in execution of arbitrary code or a Denial of Service.
|Package||media-gfx/fontforge on all architectures|
|Affected versions||< 20110222-r1|
|Unaffected versions||>= 20110222-r1|
FontForge is a PostScript font editor and converter.
FontForge is vulnerable to an error when processing the "CHARSET_REGISTRY" header in font files, which could cause a stack-based buffer overflow.
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).
There is no known workaround at this time.
All FontForge users should upgrade to the latest version:
# 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.
