Attackers can supply a crafted MNG file with MHDR, DHDR and a multi-record ORDR chunk to applications calling mng_read or mng_readdisplay, writing attacker-controlled data past the allocation and crashing the application.","cvssScore":6.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","cwes":["CWE-131"],"vendors":[],"products":[],"references":[{"url":"https://hackmd.io/@haindpwn/libmng-ordr-chunk-store-oob-write","tags":[]},{"url":"https://sourceforge.net/projects/libmng/","tags":[]},{"url":"https://sourceforge.net/projects/libmng/files/libmng-devel/2.0.3/","tags":[]},{"url":"https://www.vulncheck.com/advisories/libmng-through-2.0.3-heap-buffer-overflow-via-ordr-chunk-reader-mng-read-ordr","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
