Kerentanan Authentication Bypass by Alternate Name pada kernel util-linux, redhat hardened images. Skor CVSS 3.1 5.3 (Medium) menurut NVD.

Deskripsi (NVD)

A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.
