RHEL 8 : glibc (RHSA-2023:5455)
high Nessus Plugin ID 182608
Language:
Synopsis
The remote Red Hat host is missing one or more security updates for glibc.Description
The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:5455 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: buffer overflow in ld.so leading to privilege escalation (CVE-2023-4911)
* glibc: Stack read overflow in getaddrinfo in no-aaaa mode (CVE-2023-4527)
* glibc: potential use-after-free in getaddrinfo() (CVE-2023-4806)
* glibc: potential use-after-free in gaih_inet() (CVE-2023-4813)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL glibc package based on the guidance in RHSA-2023:5455.See Also
