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.

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>
|
|
|
|

<p>
|
|
|
|
|
There is no known workaround at this time.

|

|

<p>
|
|
|
|
|
All XEmacs users should upgrade to the latest version:
|
|
|
|
|
</p>
|
|
|
|
|
<code>
|
|
|
|
|
# emerge --sync
|
|
|
|
|
# emerge --ask --oneshot --verbose ">=app-editors/xemacs-21.4.22-r1"</code>

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.
