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-2021:3315 advisory.

- glibc: stack corruption from crafted input in cosl, sinl, sincosl, and tanl functions (CVE-2020-10029)

- glibc: stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern (CVE-2020-29573)

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-2021:3315.
