Bug 594740 – <media-libs/openjpeg-2.1.1_p20160922: Openjpeg null ptr dereference

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Ian Zimmerman 2016-09-22 01:29:28 UTC]

According to the announce on oss-security:

In convert.c:1483 and convert.c:1485, variable s is uncheck after
skip_int is called.
A null ptr will be passed to skip_int again and will cause a null ptr
dereference.

Reproducible: Always

there are some open issues for openjpeg that will be fixed in 2.0.2, so I guess we will bump it when available.

  OpenJpeg - variable s is uncheck after skip_int is called. A null ptr will
  be passed to skip_int again and will cause a null ptr dereference.

With the permission of the Gentoo Graphics project I pushed =media-libs/openjpeg-2.1.1_p20160922 into the tree: Actually we wanted to wait for an official v2.1.2 release but upstream postponed the release for another week. Because Gentoo is still at v2.1.0 which has some critical vulnerabilities which are allowing drive-by-download attacks we decided to do a snapshot release.

This snaptshot release (based on v2.1.1) from 2016-09-22 does contain all currently published security fixes, up to CVE-2016-7445:
