Common Vulnerabilities and Exposures assigned an identifier CVE-2007-3478 to the following vulnerability:
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.
Triggering the crash is dependent on a time-dependent race condition.
Only seems relevant for multi-threaded applications.
Upstream commits referring to mentioned gd bug:
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.
