RHEL 7 : glibc (Unpatched Vulnerability)

critical Nessus Plugin ID 199112

Synopsis

The remote Red Hat 7 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

- glibc: Incorrect handling of RPATH in elf/dl-load.c can be used to execute code loaded from arbitrary libraries (CVE-2017-16997)

- glibc: regular-expression match via proceed_next_node in posix/regexec.c leads to heap-based buffer over- read (CVE-2019-9169)

- The posix_spawn_file_actions_addopen function in glibc before 2.20 does not copy its path argument in accordance with the POSIX specification, which allows context-dependent attackers to trigger use-after- free vulnerabilities. (CVE-2014-4043)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
