The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The JBIG2Stream::readSegments method in JBIG2Stream.cc in Poppler before 0.24.5 does not use the correct specifier within a format string, which allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted PDF file.
