Apache HTTP Server: mod_proxy_ajp: Apache HTTP Server mod_proxy_ajp: Arbitrary code execution via heap-based buffer overflow

A flaw was found in modproxyajp of Apache HTTP Server. This heap-based buffer overflow vulnerability allows a remote attacker, by connecting to a malicious AJP Apache JServ Protocol server, to send a specially crafted message. This message can cause modproxyajp to write attacker-controlled data...

SUSE CVE-2026-86251

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-45761: Heap-based Buffer Overflow

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to versions 7.0.16 and 8.0.5, a crafted rule using mixed-case frame syntax could trigger a heap buffer overflow while Suricata is loading signatures. The issue is reached...
