Attackers can provide a crafted .y4m file lacking a terminating newline, causing unchecked EOF reads that hang the process indefinitely while consuming a full CPU core.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-835"],"vendors":[],"products":[],"references":[{"url":"https://github.com/ultravideo/kvazaar/blob/v2.3.2/src/encmain.c#L339-L357","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/commit/8a2f109be283e87008c679d635966cc034da39c6","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/issues/452","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/releases/tag/v2.3.2","tags":[]},{"url":"https://hackmd.io/@haindpwn/kvazaar-y4m-header-missing-newline-infinite-loop","tags":[]},{"url":"https://www.vulncheck.com/advisories/kvazaar-through-2.3.2-infinite-loop-dos-via-y4m-header-parser","tags":[]}],"exploitRefs":[{"url":"https://github.com/ultravideo/kvazaar/blob/v2.3.2/src/encmain.c#L339-L357","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/commit/8a2f109be283e87008c679d635966cc034da39c6","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/issues/452","tags":[]},{"url":"https://github.com/ultravideo/kvazaar/releases/tag/v2.3.2","tags":[]}],"hasPoc":true,"ai":null}
