xemacs security update

Synopsis

xemacs security update

Type/Severity

Security Advisory: Important

Topic

Updated XEmacs packages that fix a string format issue are now available.

Description

XEmacs is a powerful, customizable, self-documenting, modeless text editor.

Max Vozeler discovered several format string vulnerabilities in the
movemail utility of XEmacs. If a user connects to a malicious POP server, an
attacker can execute arbitrary code as the user running xemacs. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-0100 to this issue.

Users of XEmacs are advised to upgrade to these updated packages, which
contain backported patches to correct this issue.
