Common Vulnerabilities and Exposures assigned an identifier CVE-2010-0991 to
the following vulnerability:
Reference: BUGTRAQ:20100421 Secunia Research: imlib2
"IMAGE_DIMENSIONS_OK()" Logic Error

Multiple heap-based buffer overflows in imlib2 1.4.3 allow
context-dependent attackers to execute arbitrary code via a crafted
(1) ARGB, (2) XPM, or (3) BMP file, related to the IMAGE_DIMENSIONS_OK
macro in lib/image.h.
NOTE: We currently ship imlib 1.4.2 in Fedora (to rawhide) and the advisory noted in the SecurityFocus archives indicates that _only_ 1.4.3 is affected, not previous versions (verified by checking our imlib2 source; there is no IMAGE_DIMENSIONS_OK() macro). However, 1.4.3 is the current version available for download, so this is to ensure that if imlib2 does get updated to 1.4.3, it includes a fix, or we skip it and wait for 1.4.4 to be released. The advisory also indicates this is fixed in upstream svn:
--- image.h (revision 43242)
+++ image.h (revision 47825)

I see new 1.4.3 builds in koji that include the patch. Thank you for including the patch!
So the 1.4.3 builds in Fedora 13 and rawhide contain the patch to correct this flaw.
