Description Tomas Hoger 2009-05-22 06:41:36 UTC
It was discovered that original upstream patch for server-side command execution flaw affecting setups with map_yp_alias username map enabled did not address the issue completely, due to incorrect use of quoting (backticks vs. single quotes).  Code execution was still possible in upstream version 1.4.18.

Issue was fixed upstream in 1.4.19.

Comment 5 Jan Lieskovsky 2009-05-25 07:14:58 UTC
CVE-2009-1381:

The map_yp_alias function in functions/imap_general.php in
SquirrelMail before 1.4.19-1 on Debian GNU/Linux, and possibly other
operating systems and versions, allows remote attackers to execute
arbitrary commands via shell metacharacters in a username string that
is used by the ypmatch program. NOTE: this issue exists because of an
incomplete fix for CVE-2009-1579.
