CVE-2025-53537 unimportant priority: Debian including 1 source packages (libhtp), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
LibHTP is a security-aware parser for the HTTP protocol and its related bits and pieces. In versions 0.5.50 and below, there is a traffic-induced memory leak that can starve the process of memory, leading to loss of visibility. To workaround this issue, set `suricata.yaml app-layer.protocols.http.libhtp.default-config.lzma-enabled` to false. This issue is fixed in version 0.5.51.
