RHEL 7 : glibc (RHSA-2024:3588)

high Nessus Plugin ID 200095

Synopsis

The remote Red Hat host is missing one or more security updates for glibc.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:3588 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: Out of bounds write in iconv may lead to remote code execution (CVE-2024-2961)

 * glibc: stack-based buffer overflow in netgroup cache (CVE-2024-33599)

 * glibc: null pointer dereferences after failed netgroup cache insertion (CVE-2024-33600)

 * glibc: netgroup cache may terminate daemon on memory allocation failure (CVE-2024-33601)

 * glibc: netgroup cache assumes NSS callback uses in-buffer strings (CVE-2024-33602)

 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-2024:3588.
