CVE-2010-2055

Publication date 22 July 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Ghostscript 8.71 and earlier reads initialization files from the current working directory, which allows local users to execute arbitrary PostScript commands via a Trojan horse file, related to improper support for the -P- option to the gs program, as demonstrated using gs_init.ps, a different vulnerability than CVE-2010-4820.

Notes

mdeslaur

There are three different issues here: 1- -P is the default, and not -P- 2- -P- doesn't actually work 3- ghostscript's scripts don't use -P- Fixing this will change the default behaviour, and may introduce regressions in software in the archive, and custom software. Since this is primarily a user-assisted attack, the risks of fixing this outweighs the advantages. Marking as ignored for affected releases.
