Description Ratul Gupta 2014-01-03 11:21:40 UTC

Poppler was recently reported to be vulnerable to a flaw, which can be exploited by malicious people to cause a DoS (Denial of Service) in an application using the library.

The vulnerability is caused due to a format string error when handling extraneous bytes within a segment in the "JBIG2Stream::readSegments()" method in JBIG2Stream.cc, which can be exploited to cause a crash.

The issue is said to be fixed in Poppler 0.24.5.

Comment 5 Fedora Update System 2014-01-05 06:07:13 UTC

Comment 6 Huzaifa S. Sidhpurwala 2014-01-06 08:13:09 UTC

In the version of poppler shipped with Red Hat Enterprise Linux 5 and 6, vulnerable format string is not used. Upstream uses "{0:d}" while the Red Hat Enterprise Linux version uses "%d". Secondly the upstream version of poppler uses a custom defined error() function (in poppler/Error.cc), while in the Red Hat Enterprise Linux version, error() is just a wrapper around the glibc error() function.

Therefore this issue does not affect the version of poppler in Red Hat Enterprise Linux 5 and 6.

Comment 7 Huzaifa S. Sidhpurwala 2014-01-06 08:14:21 UTC

Statement:

Not Vulnerable. This issue does not affect the version of poppler as shipped with Red Hat Enterprise Linux 5 and 6.
