Prior to 2.7.8, create_sample_file() in libmport/bundle_read_install_pkg.c did not constrain absolute source and destination paths from the sample-file manifest directive to mport->root. A malicious or malformed package manifest could therefore direct privileged sample-file handling to copy or write outside the configured installation root, compromising local filesystem integrity. This issue is fixed in version 2.7.8.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MidnightBSD/mport/commit/36a42c8ddbd23ee9eb72c4c17596eb92cb423cf0","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/122","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-xqjc-rxmm-p27v","tags":[]}],"exploitRefs":[{"url":"https://github.com/MidnightBSD/mport/commit/36a42c8ddbd23ee9eb72c4c17596eb92cb423cf0","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/122","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-xqjc-rxmm-p27v","tags":[]}],"hasPoc":true,"ai":null}
