CVE-2014-0012

Publication date 19 May 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

FileSystemBytecodeCache in Jinja2 2.7.2 does not properly create temporary directories, which allows local users to gain privileges by pre-creating a temporary directory with a user's uid. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-1402.

Notes

mdeslaur

Introduced in 2.7.2, and in CVE-2014-1402 security fix. 2.7.2-2 in trusty switches to tempfile.mkdtemp which fixes the security issue, but isn't an ideal fix for proper caching.
