More information:

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.
