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

In libwebm through 2018-10-03, there is an abort caused by libwebm::Webm2Pes::InitWebmParser() that will lead to a DoS attack.

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.
