Summary
protobuf-c vulnerability
Details

Pietro Borrello discovered that protobuf-c contained an invalid arithmetic shift. This vulnerability allowed attackers to cause a denial of service (system crash) via unspecified vectors (CVE-2022-33070).

It was discovered that protobuf-c contained an unsigned integer overflow. This vulnerability allowed attackers to cause a denial of service (system crash) via unspecified vectors.

Todd Miller discovered that protobuf-c contained a possible NULL dereference. This could cause a vulnerability that allowed attackers to cause a denial of service (system crash) via unspecified vectors.
