3 November 2008

enscript vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 8.10
  • Ubuntu 8.04 LTS
  • Ubuntu 7.10
  • Ubuntu 6.06 LTS

Software Description

  • enscript

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 8.10
enscript - 1.6.4-12ubuntu0.8.10.1
Ubuntu 8.04 LTS
enscript - 1.6.4-12ubuntu0.8.04.1
Ubuntu 7.10

Ubuntu 6.06 LTS
enscript - 1.6.4-7ubuntu0.2
