Oracle Linux: CVE-2022-48303: ELSA-2023-0842: tar security update (MODERATE) (Multiple Advisories)
Description
GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters. A flaw was found in the Tar package. When attempting to read files with old V7 tar format with a specially crafted checksum, an invalid memory read may occur. An attacker could possibly use this issue to expose sensitive information or cause a crash.
