A vulnerability was determined in FLVMeta up to 1.2.2. Affected by this vulnerability is the function amf_object_get of the file src/amf.c of the component AMF Object Parsing. This manipulation causes null pointer dereference. The attack may be initiated remotely. The exploit has been publicly disclosed and may be utilized. Patch name: 52642f7dfb76ec7334016622dde60b1ae963d79b. To fix this issue, it is recommended to deploy a patch. The project maintainer doubts the security impact: "While I acknowledged the bugs and provided fixes, I have yet to see any way to exploit these alleged vulnerabilities."
AnalysisAI
Null pointer dereference in FLVMeta up to 1.2.2 causes a process crash when parsing a malformed AMF object from a crafted FLV file, resulting in denial of service. The flaw resides in amf_object_get (and the parallel amf_object_set) in src/amf.c, where a chained double dereference node->next->next executes without first confirming node->next is non-NULL. …
