Debian DSA-034-1 : ePerl - remote root exploit

high Nessus Plugin ID 14871

Synopsis

The remote Debian host is missing a security-related update.

Description

Fumitoshi Ukai and Denis Barbier have found several potential buffer overflow bugs in our version of ePerl as distributed in all of our distributions.

When eperl is installed setuid root, it can switch to the UID/GID of the scripts owner. Although Debian doesn't ship the program setuid root, this is a useful feature which people may have activated locally. When the program is used as /usr/lib/cgi-bin/nph-eperl the bugs could lead into a remote vulnerability as well.

Version 2.2.14-0.7potato2 fixes this; we recommend you upgrade your eperl package immediately.

Solution

Upgrade the affected eperl package.
