XEmacs: User-assisted execution of arbitrary code
Gentoo Linux Security Advisory
||GLSA 201006-15 / xemacs
||June 03, 2010
||June 03, 2010: 01
All supported architectures
Multiple integer overflow errors in XEmacs might allow remote,
user-assisted attackers to execute arbitrary code.
XEmacs is a highly extensible and customizable text editor.
Tielei Wang reported multiple integer overflow vulnerabilities in the
tiff_instantiate(), png_instantiate() and jpeg_instantiate() functions
in glyphs-eimage.c, all possibly leading to heap-based buffer
A remote attacker could entice a user to open a specially crafted TIFF,
JPEG or PNG file using XEmacs, possibly resulting in the remote
execution of arbitrary code with the privileges of the user running the
application, or a Denial of Service condition.
There is no known workaround at this time.
All XEmacs users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/xemacs-21.4.22-r1"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since July 26, 2009. It is likely that your system is already
no longer affected by this issue.
