L-SMASH through 2.14.5 Infinite Loop in VC-1 Importer Probe
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
L-SMASH through 2.14.5 contains an infinite loop vulnerability in vc1_importer_probe() in importer/vc1_imp.c that allows attackers to hang applications via crafted input files. Attackers can supply a file consisting only of zero bytes, which lsmash_read_file() probes automatically, causing indefinite CPU consumption and denial of service.
