Severity ?
2.0 (Low) - CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
CWE
  • CWE-354 - Improper Validation of Integrity Check Value
  • CWE-755 - Improper Handling of Exceptional Conditions
Summary
mport is the MidnightBSD Package Manager. 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.
