Synopsis

The remote Red Hat host is missing a security update for glibc.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2025:10220 advisory.

The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.

Security Fix(es):

* glibc: static setuid binary dlopen may incorrectly search LD_LIBRARY_PATH (CVE-2025-4802)
