Multiple Services such as VHS(Video History Server) and VCD(Video Clip Distributor) and Clips2 were discovered to be vulnerable to an unauthenticated arbitrary file read/write vulnerability due to missing input validation on filenames. A malicious attacker could read sensitive files from the filesystem or write/delete arbitrary files on the filesystem as well.

H3C Magic B1STW B1STV100R012 was discovered to contain a stack overflow via the function SetAPInfoById. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.

An issue in Ateme Flamingo XL v.3.6.20 and XS v.3.6.5 allows a remote authenticated attacker to execute arbitrary code and cause a denial of service via a the session expiration function.

Widevine Trusted Application (TA) 5.0.0 through 5.1.1 has a drm_save_keys file_name_len integer overflow and resultant buffer overflow.

Widevine Trusted Application (TA) 5.0.0 through 5.1.1 has a drm_verify_keys prefix_len+feature_name_len integer overflow and resultant buffer overflow.

Widevine Trusted Application (TA) 5.0.0 through 7.1.1 has a PRDiagParseAndStoreData integer overflow and resultant buffer overflow.

Widevine Trusted Application (TA) 5.0.0 through 7.1.1 has a PRDiagVerifyProvisioning integer overflow and resultant buffer overflow.

Widevine Trusted Application (TA) 5.0.0 through 5.1.1 has a drm_verify_keys total_len+file_name_len integer overflow and resultant buffer overflow.

Widevine Trusted Application (TA) 5.0.0 through 5.1.1 has a drm_save_keys integer overflow and resultant buffer overflow.

### 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...
