AXSA:2025-10920:15 advisory.

    * CVE-2025-4802: prevent untrusted LD_LIBRARY_PATH from loading   dynamically shared libraries in
    statically compiled binaries that call   dlopen
    * CVE-2019-9169: fix heap-based buffer over-read in proceed_next_node function   in posix/regexec.c
    CVE(s):
    CVE-2025-4802
    Untrusted LD_LIBRARY_PATH environment variable vulnerability in the GNU C Library version 2.27 to 2.38
    allows attacker controlled loading of dynamically shared library in statically compiled setuid binaries
    that call dlopen (including internal dlopen calls after setlocale or calls to NSS functions such as
    getaddrinfo).
    CVE-2019-9169
    In the GNU C Library (aka glibc or libc6) through 2.29, proceed_next_node in posix/regexec.c has a heap-
    based buffer over-read via an attempted case-insensitive regular-expression match.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
