Detail

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.

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:
# 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.
