- Summary
- LibHTP's memory leak with lzma can lead to resource starvation
- Details

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-enabledto false. This issue is fixed in version 0.5.51. - Database specific
