CentOS Linux 7 [TuxCare] Security Update: sysstat Multiple Vulnerabilities (CENTOS7:CLSA-2023:1697464186)

high Nessus Plugin ID 361132

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2023:1697464186 advisory.

 - sysstat is a set of system performance tools for the Linux operating system. On 32 bit systems, in versions 9.1.16 and newer but prior to 12.7.1, allocate_structures contains a size_t overflow in sa_common.c. The allocate_structures function insufficiently checks bounds before arithmetic multiplication, allowing for an overflow in the size allocated for the buffer representing system activities. This issue may lead to Remote Code Execution (RCE). This issue has been patched in version 12.7.1. (CVE-2022-39377)

 - sysstat through 12.7.2 allows a multiplication integer overflow in check_overflow in common.c. NOTE: this issue exists because of an incomplete fix for CVE-2022-39377. (CVE-2023-33204)

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 affected sysstat package based on the guidance in TuxCare advisory CENTOS7:CLSA-2023:1697464186.
