The allocation fails and Imager's allocator calls exit(3).\n\nReading an attacker-supplied file through Imager->read() triggers an uncatchable exit.","cvssScore":9.1,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","cwes":["CWE-196","CWE-789"],"vendors":[],"products":[],"references":[{"url":"https://github.com/tonycoz/imager/commit/74ed50e0625f9f51054e595bb4a8da92c1e0d571.patch","tags":[]},{"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-p4vw-rc54-p2c2","tags":[]},{"url":"https://metacpan.org/release/TONYC/Imager-1.036/changes","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/18/9","tags":[]},{"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-p4vw-rc54-p2c2","tags":[]}],"exploitRefs":[{"url":"https://github.com/tonycoz/imager/commit/74ed50e0625f9f51054e595bb4a8da92c1e0d571.patch","tags":[]},{"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-p4vw-rc54-p2c2","tags":[]},{"url":"https://github.com/tonycoz/imager/security/advisories/GHSA-p4vw-rc54-p2c2","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to cause the Imager Perl module to exit unexpectedly by providing a TGA file with a colour map length of 32768 or more, leading to a denial of service.","exploitability":"Exploitation is relatively straightforward as it requires only crafting a specific TGA file and reading it through Imager's API.
