Synopsis ========
A heap-based buffer overflow in SWFTools could result in the execution of arbitrary code.
Background ==========
SWFTools is a collection of SWF manipulation and generation utilities written by Rainer Böhme and Matthias Kramm.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/swftools <= 0.9.1 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers.
Description ===========
Integer overflow errors in the "getPNG()" function in png.c and the "jpeg_load()" function in jpeg.c could cause a heap-based buffer overflow.
Impact ======
A remote attacker could entice a user to open a specially crafted PNG or JPEG file, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
Gentoo discontinued support for SWFTools. We recommend that users unmerge swftools:
# emerge --unmerge "media-gfx/swftools"
References ==========
