Synopsis

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

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 :

 # emerge --sync # emerge --ask --oneshot --verbose '>=media-libs/jbig2dec-0.13-r4'
