Description Andrej Nemec 2017-01-12 13:54:16 UTC

A vulnerability was found in libebml. A specially crafted unicode string can cause an off-by-few read on the heap in unicode string parsing code in libebml. This issue can potentially be used for information leaks.

Comment 2 Dominik 'Rathann' Mierzejewski 2017-01-12 22:54:53 UTC

Upon closer investigation, I believe this is a duplicate of CVE-2015-8790 (bug 1303861) and will close it as such upon confirmation from upstream.
