Severity: High Title: Xmail: Privilege escalation through sendmail Date: December 14, 2005 Bugs: #109381 ID: 200512-05

Synopsis ========
The sendmail program in Xmail is vulnerable to a buffer overflow, potentially resulting in local privilege escalation.
Background ==========
Xmail is an Internet and intranet mail server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-mta/xmail < 1.22 >= 1.22
Description ===========
iDEFENSE reported that the AddressFromAtPtr function in the sendmail program fails to check bounds on arguments passed from other functions, and as a result an exploitable stack overflow condition occurs when specifying the "-t" command line option.
Impact ======
A local attacker can make a malicious call to sendmail, potentially resulting in code execution with elevated privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Xmail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-mta/xmail-1.22"
