Gentoo Linux Security Advisory

Title: XEmacs: User-assisted execution of arbitrary code (GLSA 201006-15)
Severity: normal
Exploitable: remote
Date: June 03, 2010
Bug(s): #275397
ID: 201006-15

Synopsis


Multiple integer overflow errors in XEmacs might allow remote,
user-assisted attackers to execute arbitrary code.


Background


XEmacs is a highly extensible and customizable text editor.


Affected Packages

Package: app-editors/xemacs
Vulnerable: < 21.4.22-r1
Unaffected: >= 21.4.22-r1
Architectures: All supported architectures


Description


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
overflows.


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All XEmacs users should upgrade to the latest version:
Code:
# 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.
