Photon OS 3.0: Glibc PHSA-2021-3.0-0281

critical Nessus Plugin ID 152502

Synopsis

The remote PhotonOS host is missing multiple security updates.

Description

An update of the glibc package has been released.

- The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations. (CVE-2021-35942)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected Linux packages.
