Description Tomas Hoger 2010-06-25 12:04:14 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2010-2443 to the following vulnerability:

OJPEG image with undefined strip offsets.

Comment 1 Tomas Hoger 2010-06-25 12:09:03 UTC

This CVE refers to following entry in the upstream changelog:

  OJPEG: Report an error and avoid a crash if the input file is so broken
  that the strip offsets are not defined.

This problem is already tracked as bug #603024.  We are not handling this as security flaw, this NULL pointer dereference flaw with impact limited to application crash.

Statement:

Not vulnerable. This issue did not affect the versions of libtiff as shipped with Red Hat Enterprise Linux 3, 4, or 5.
