Description


A vulnerability has been reported in the PEAR Mail package, which can be exploited by malicious people to bypass certain security restrictions.

The sendmail implementation of the "Mail::Send()" method does not properly sanitise the "from" parameter before invoking sendmail, which can be exploited to pass arbitrary arguments to the sendmail command.

Successful exploitation requires that the sendmail implementation is used and that the attacker is able to define the "from" or parameter.

The vulnerability is reported in version 1.1.14. Other versions may also be affected.


Solution:
Fixed in version 1.2.0b2.

Provided and/or discovered by:
Reported in a PEAR bug by "websec".
