Recent Webmproject Libwebm Security Vulnerabilities
In libwebm before 2019-03-08, a NULL pointer dereference caused by the functions OutputCluster and OutputTracks in webm_info.cc will trigger an abort, which
CVE-2019-9746
7.5 - High
- March 13, 2019
In libwebm before 2019-03-08, a NULL pointer dereference caused by the functions OutputCluster and OutputTracks in webm_info.cc will trigger an abort, which allows a DoS attack, a similar issue to CVE-2018-19212.
NULL Pointer Dereference
In libwebm through 2018-10-03, there is an abort caused by libwebm::Webm2Pes::InitWebmParser()
CVE-2018-19212
6.5 - Medium
- November 12, 2018

Always-Incorrect Control Flow Implementation
A use-after-free issue was discovered in libwebm through 2018-02-02
CVE-2018-6548
9.8 - Critical
- February 02, 2018
A use-after-free issue was discovered in libwebm through 2018-02-02. If a Vp9HeaderParser was initialized once before, its property frame_ would not be changed because of code in vp9parser::Vp9HeaderParser::SetFrame. Its frame_ could be freed while the corresponding pointer would not be updated, leading to a dangling pointer. This is related to the function OutputCluster in webm_info.cc.
Dangling pointer
The function ParseVP9SuperFrameIndex in common/libwebm_util.cc in libwebm through 2018-01-30 does not validate the child_frame_length data obtained from a .webm file, which
CVE-2018-6406
8.8 - High
- January 30, 2018
The function ParseVP9SuperFrameIndex in common/libwebm_util.cc in libwebm through 2018-01-30 does not validate the child_frame_length data obtained from a .webm file, which allows remote attackers to cause an information leak or a denial of service (heap-based buffer over-read and later out-of-bounds write), or possibly have unspecified other impact.
Out-of-bounds Read
