Package        : sysstat
Version        : 12.0.3-2+deb10u1
CVE ID         : CVE-2019-16167 CVE-2019-19725 CVE-2022-39377
Debian Bug     : 939914 946657 1023832

There were a couple of secuity issues found in sysstat, system
performance tools for Linux, which are as follows:

CVE-2019-16167

    sysstat before 12.1.6 has memory corruption due to an Integer
    Overflow in remap_struct() in sa_common.c.

CVE-2019-19725

    sysstat through 12.2.0 has a double free in check_file_actlst
    in sa_common.c.

CVE-2022-39377

    On 32 bit systems, 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).

For Debian 10 buster, these problems have been fixed in version
12.0.3-2+deb10u1.

We recommend that you upgrade your sysstat packages.
