CVE-2026-112008

MEDIUMCVSS 6.1/10

Last modified

CVE-2026-112008 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. libmng through 2.0.3 contains a heap-based buffer overflow vulnerability in mng_read_ordr() that allows attackers to corrupt heap memory because ORDR entry buffers are sized by 5-byte on-wire records instead of 8-byte in-memory entries. 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..
