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.
