Convert-UUlib: Buffer overflow

Background

Convert-UUlib provides a Perl interface to the uulib library, allowing Perl applications to access data encoded in a variety of formats.

Description

A vulnerability has been reported in Convert-UUlib where a malformed parameter can be provided by an attacker allowing a read operation to overflow a buffer. The vendor credits Mark Martinec and Robert Lewis with the discovery.

Impact

Successful exploitation would permit an attacker to run arbitrary code with the privileges of the user running the Perl application.

Workaround

There is no known workaround at this time.

Resolution

All Convert-UUlib users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-perl/Convert-UUlib-1.051"
