Medium Nessus Plugin ID 102799


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-201708-10 (jbig2dec: User-assisted execution of arbitrary code)

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.


All jbig2dec users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/jbig2dec-0.13-r4'
