Description Lubomir Kundrak 2007-09-04 19:52:49 UTC

Race condition in gdImageStringFTEx (gdft_draw_bitmap) in gdft.c in the GD Graphics Library (libgd) before 2.0.35 allows user-assisted remote attackers to cause a denial of service (crash) via unspecified vectors, possibly involving truetype font (TTF) support.

Comment 1 Lubomir Kundrak 2007-09-04 19:55:15 UTC 
Triggering the crash is dependent on a time-dependent race condition.
Comment 3 Tomas Hoger 2008-02-08 17:20:09 UTC 
Only seems relevant for multi-threaded applications.

Comment 4 Tomas Hoger 2008-02-13 15:55:02 UTC 
We currently do not plan to backport a fix for this issue to gd packages in
current versions of Red Hat Enterprise Linux 2.1, 3, 4, and 5 due to low
likelihood of application possibly affected by this problem being exposed in a
way that would allow trust boundary to be crossed.
