It was discovered that sysstat, a system performance tools for Linux, incompletely fixed CVE-2022-39377 (as published in DLA-3188-1), which could lead to crashes and possibly remote code execution.

  • CVE-2023-33204

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

    For reference, the initial vulnerability was:

  • 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+deb10u2.

We recommend that you upgrade your sysstat packages.
