|---|---|---|---|---|---|---|
| CVE-2019-9746 | 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. | [email protected] | 7.5 | 0.34% | 2019-03-13 | 2024-11-21 |
| CVE-2018-19212 | In libwebm through 2018-10-03, there is an abort caused by libwebm::Webm2Pes::InitWebmParser() that will lead to a DoS attack. | [email protected] | 6.5 | 0.24% | 2018-11-12 | 2024-11-21 |
| CVE-2018-6548 | 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. | [email protected] | 9.8 | 0.53% | 2018-02-02 | 2024-11-21 |
| CVE-2018-6406 | 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. | [email protected] | 8.8 | 0.45% | 2018-01-30 | 2024-11-21 |
