Last modified: 2017-07-11 15:30:05 UTC
A crafted AVI file can cause a segmentation fault due to invalid memory read access. upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=777532 upstream commit: https://github.com/GStreamer/gst-plugins-good/commit/4f47835 acknowledgments: Hanno Böck References: https://bugzilla.redhat.com/show_bug.cgi?id=1419582 http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-5845 http://seclists.org/oss-sec/2017/q1/284 http://people.canonical.com/~ubuntu-security/cve/2017/CVE-2017-5845.html http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5845 https://bugzilla.gnome.org/show_bug.cgi?id=777955 https://bugzilla.gnome.org/show_bug.cgi?id=777957
Only SLE-12-SP2 containts the ncdt tag parsing code in SUSE:SLE-12-SP2:Update/gstreamer-plugins-good/gst-plugins-good-1.8.3/gst/avi/gstavidemux.c:3879 The older codestream does not contain that function and the PoC file doesn't trigger. Note that there might be a dependency to bug 1024030. QA reproducer: Using the file from https://samples.mplayerhq.hu/ffmpeg-bugs/trac/ticket3330/DSCN0902.AVI I've been able to reproduce the issue on SLES-12-SP2 like this: gst-discoverer-1.0 DSCN0902.AVI The program will abort due to a segmentation fault.
