Ubuntu 16.04 ESM : APR vulnerability (USN-5056-1)

high Nessus Plugin ID 152918

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 21.04 host has packages installed that are affected by a vulnerability as referenced in the USN-5056-1 advisory.

 - An out-of-bounds array read in the apr_time_exp*() functions was fixed in the Apache Portable Runtime 1.6.3 release (CVE-2017-12613). The fix for this issue was not carried forward to the APR 1.7.x branch, and hence version 1.7.0 regressed compared to 1.6.3 and is vulnerable to the same issue. (CVE-2021-35940)

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 libapr1 and / or libapr1-dev packages.
