Narrative and Response

Description

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, HTTP SWF decompression with the non-default swf-decompression feature and an unsafe decompress-depth can use the configured depth when allocating in src/util-file-decompression.c instead of limiting the allocation to the Flash file's actual data requirement. A crafted SWF response can therefore trigger an integer-related heap buffer overflow and crash Suricata; the default disabled feature and default depth are not affected. This issue is fixed in versions 8.0.6 and 7.0.17.
