Suricata · Suricata · CVE-2026-57226
**Name of the Vulnerable Software and Affected Versions**
Suricata versions prior to 7.0.17
Suricata versions prior to 8.0.6
**Description**
HTTP SWF decompression, when using the non-default `swf-decompression` feature and an unsafe `decompress-depth`, may use the configured depth for allocation in `src/util-file-decompression.c` instead of limiting it to the actual data requirement of the Flash file. A specially crafted SWF response can trigger an integer-related heap buffer overflow, leading to a crash of the system. The default disabled state of the feature and the default depth are not affected.
**Recommendations**
Update to version 7.0.17 or later.
Update to version 8.0.6 or later.
As a temporary mitigation, disable the `swf-decompression` feature.
