Amazon Linux AMI : libXpm (ALAS-2023-1875)

high Nessus Plugin ID 184386

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of libXpm installed on the remote host is prior to 3.5.10-2.12. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1875 advisory.

- A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
(CVE-2023-43786)

- A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges. (CVE-2023-43787)

- A vulnerability was found in libXpm where a vulnerability exists due to a boundary condition, a local user can trigger an out-of-bounds read error and read contents of memory on the system. (CVE-2023-43789)

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

Solution

Run 'yum update libXpm' to update your system.
