Summary:

Several security issues were fixed in protobuf-c.

Software Description:
- protobuf-c: Protocol Buffers C static library and headers (protobuf-c)

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.

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
