Package : sysstat Version : 12.5.2-2+deb11u1 CVE ID : CVE-2022-39377 CVE-2023-33204

An issue has been found in sysstat, a system performance tools for Linux.

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).

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 (see above).

For Debian 11 bullseye, these problems have been fixed in version 12.5.2-2+deb11u1.

We recommend that you upgrade your sysstat packages.
