|Gentoo Linux Security Advisory
Title: Xmail: Privilege escalation through sendmail (GLSA 200512-05)
Date: December 14, 2005
The sendmail program in Xmail is vulnerable to a buffer overflow,
potentially resulting in local privilege escalation.
Xmail is an Internet and intranet mail server.
Vulnerable: < 1.22
Unaffected: >= 1.22
Architectures: All supported architectures
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.
A local attacker can make a malicious call to sendmail,
potentially resulting in code execution with elevated privileges.
There is no known workaround at this time.
All Xmail users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-mta/xmail-1.22"
