Hi,

The following vulnerability was published for sysstat.

CVE-2022-39377[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
