httpd: mod_proxy_ajp: off-by-one out-of-bounds reads in AJP getter functions

A flaw was found in the modproxyajp module of httpd. When processing AJP Apache JServ Protocol messages, the AJP getter functions attempt to read data beyond the allocated buffer size, allowing an attacker or a malformed request to cause an out-of-bounds read. This issue leads to a denial of...

CVE-2026-58380

A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscannergettoken function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption,...
