What is CVE-2022-48303?

GNU Tar versions up to 1.34 contain an out-of-bounds read vulnerability that can lead to the use of uninitialized memory. This flaw manifests in the 'from_header' function within the list.c file when processing a V7 archive that includes an mtime with approximately 11 whitespace characters. While exploiting this issue to manipulate control flow has not been demonstrated, it raises concerns about the security of applications relying on GNU Tar for archiving and data manipulation.
