### Summary Due to the misuse of `log.Fatalf`, the application using coraza crashed after receiving crafted requests from attackers. ### Details https://github.com/corazawaf/coraza/blob/82157f85f24c6107667bf0f686b71a72aafdf8a5/internal/bodyprocessors/multipart.go#L26-L29 The bodyprocessors of multipart uses `log.Fatalf` to handle errors from the `mime.ParseMediaType`, but `log.Fatalf` calls `os.Exit` directly after logging the error. https://github.com/golang/go/blob/a031f4ef83edc132d5f49382bfef491161de2476/src/log/log.go#L288-L291 This means that the application will immediately crash after receiving a malicious request that triggers an error in `mime.ParseMediaType`. ### PoC The server can be demonstrated by https://github.com/corazawaf/coraza/tree/main/examples/http-server After sending this request ``` POST / HTTP/1.1 Host: 127.0.0.1:8090 User-Agent: curl/8.1.2 Accept: */* Content-Length: 199 Content-Type: multipart/form-data; boundary=------------------------5fa6351b877326a1...

Shibboleth XMLTooling before 3.2.4, as used in OpenSAML and Shibboleth Service Provider, allows SSRF via a crafted KeyInfo element. (This is fixed in, for example, Shibboleth Service Provider 3.4.1.3 on Windows.)

end_pattern (called from internal_fnmatch) in the GNU C Library (aka glibc or libc6) before 2.22 might allow context-dependent attackers to cause a denial of service (application crash), as demonstrated by use of the fnmatch library function with the **(!() pattern. NOTE: this is not the same as CVE-2015-8984; also, some Linux distributions have fixed CVE-2015-8984 but have not fixed this additional fnmatch issue.
