[GLSA-200512-05] Xmail: Privilege escalation through sendmail Vulnerability Scan
Vulnerability Scan Summary
Xmail: Privilege escalation through sendmail
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200512-05
(Xmail: Privilege escalation through sendmail)
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 rights.
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"
Threat Level: High
