Advisory: RHSA-2005:755-07
Type: Security Advisory
Severity: Critical
Issued on: 2005-08-23
Last updated on: 2005-08-23

CVEs (cve.mitre.org): CVE-2005-2665

Details

An updated elm package is now available that fixes a buffer overflow issue
for Red Hat Enterprise Linux 2.1 AS and AW.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Elm is a terminal mode email client.

A buffer overflow flaw in Elm was discovered that was triggered by viewing
a mailbox containing a message with a carefully crafted 'Expires' header.
An attacker could create a malicious message that would execute arbitrary
code with the privileges of the user who received it. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2005-2665 to this issue.

Users of Elm should update to this updated package, which contains a
backported patch that corrects this issue.
