Description Vincent Danen 2012-07-19 20:11:39 UTC

The at-spi2-atk module for GTK+ was found [1],[2] to not handle temporary files in a secure manner.  The /tmp/at-spi2/ directory that it uses is world-writable and readable, and uses a predictable hard-coded name.  This could lead to symlink attacks, overwriting arbitrary files.

This has been fixed in upstream version 2.5.3, via git commit e4f3ee [3].

Created at-spi2-atk tracking bugs for this issue

Affects: fedora-all [bug 841671]

This still affects Fedora 17, but Fedora 18 has a post-fix upstream version.
