Doc Text:
An integer overflow vulnerability was found in sysstat in the way the `sadf` command processes the contents of data files created by the `sar` command. A local attacker could exploit this flaw by creating a specially crafted file with malformed data that, when loaded by a victim, causes the application to crash.

Upstream commit:

Comment 1 Guilherme de Almeida Suckevicz 2019-11-05 17:02:06 UTC
Created sysstat tracking bugs for this issue:

Affects: fedora-all [bug 1768971]

Comment 2 Mauro Matteo Cascella 2020-01-13 16:01:15 UTC

This issue did not affect the versions of sysstat as shipped with Red Hat Enterprise Linux 5, 6, and 7 as they did not include the vulnerable function, which was introduced in a newer version of the package.

Comment 3 Mauro Matteo Cascella 2020-01-13 16:22:25 UTC
The vulnerable function remap_struct() is used to map structures containing statistics from two different sysstat versions.
This function was introduced upstream in version v11.7.1 with the following commit: https://github.com/sysstat/sysstat/commit/65ac30359e49ee717397e39950d7c24a6610d57c
