Synopsis ========
Multiple integer overflow flaws have been discovered in jbig2dec, possibly resulting in execution of arbitrary code or Denial of Service.
Background ==========
jbig2dec is a decoder implementation of the JBIG2 image compression format.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/jbig2dec < 0.13-r4 >= 0.13-r4
Description ===========
Integer overflow errors have been discovered in the jbig2_decode_symbol_dict, jbig2_build_huffman_table, and jbig2_image_compose functions of jbig2dec.
Impact ======
A remote attacker, by enticing a user to open a specially crafted JBIG2 file using an application linked against jbig2dec, could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All jbig2dec users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/jbig2dec-0.13-r4"
