Kerentanan NULL Pointer Dereference pada libarchive, redhat hardened images +2 lainnya. Skor CVSS 3.1 5.5 (Medium) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a Denial of Service (DoS).
