LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. Prior to version 0.5.49, unbounded processing of HTTP request and response headers can lead to excessive CPU time and memory utilization, possibly leading to extreme slowdowns. This issue is addressed in 0.5.49.

HIGH7.5

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.
