{"id":"UBUNTU-CVE-2022-36227","details":"In libarchive before 3.6.2, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference. NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: \"In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.\"","modified":"2026-04-22T15:37:33.019657Z","published":"2022-11-22T02:15:00Z","related":["USN-7070-1"],"upstream":["CVE-2022-36227"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-36227"},{"type":"REPORT","url":"https://github.com/libarchive/libarchive/pull/1759"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-36227"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7070-1"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/libarchive@3.1.2-7ubuntu2.8+esm3?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2-7ubuntu2.8+esm3"}]}],"versions":["3.1.2-5ubuntu1","3.1.2-7ubuntu1","3.1.2-7ubuntu2","3.1.2-7ubuntu2.1","3.1.2-7ubuntu2.2","3.1.2-7ubuntu2.3","3.1.2-7ubuntu2.4","3.1.2-7ubuntu2.6","3.1.2-7ubuntu2.7","3.1.2-7ubuntu2.8","3.1.2-7ubuntu2.8+esm1"],"ecosystem_specific":{"availability":"Available
