Description

This is a simple case of a vsprintf overflowing a statically allocated buffer. I've done a build of plib for rawhide switching to vsnprintf. I've not created updated builds for F-15 / F-16, since the overflow will be caught by FORTIFY_SOURCE (and plib is compiled with that), so this poses no more thread then a DOS. Let me know if the security team wants me to also issue fixed packages for F-15 and F-16. If you could, yes. I'll file trackers for it. Even though it is just a DoS, we should correct it. Created plib tracking bugs for this issue Affects: fedora-all [bug 771502] plib-1.8.5-5.fc15 has been pushed to the Fedora 15 stable repository. If problems still persist, please make note of it in this bug report. plib-1.8.5-5.fc16 has been pushed to the Fedora 16 stable repository.
