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.

For the detailed security status of sysstat please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
