Prior to 2.7.8, mport_verify_package() in libmport/verify.c could continue after MD5File() or SHA256_File() failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed file or the conditions that make hashing fail could receive a misleading integrity result or hide a checksum failure. This issue is fixed in version 2.7.8.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-354","CWE-755"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MidnightBSD/mport/commit/cd9991c3cc1f60ecb3f378852ad8b5caa820e990","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/138","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-hgmr-9p75-q5cg","tags":[]}],"exploitRefs":[{"url":"https://github.com/MidnightBSD/mport/commit/cd9991c3cc1f60ecb3f378852ad8b5caa820e990","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/138","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-hgmr-9p75-q5cg","tags":[]}],"hasPoc":true,"ai":null}
