A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 8.10
- Ubuntu 8.04 LTS

Software description

Details
Ulf Härnhammar discovered multiple stack overflows in enscript's handling of
special escape arguments. If a user or automated system were tricked into
processing a malicious file with the "-e" option enabled, a remote attacker
could execute arbitrary code or cause enscript to crash, possibly leading
to a denial of service.
