CVE-2022-39377: Debian Linux

High severity, CVSS 7.8. EPSS: 1.2% chance of exploitation in the next 30 days.

sysstat is a set of system performance tools for the Linux operating system. On 32 bit systems, in versions 9.1.16 and newer but prior to 12.7.1, 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). This issue has been patched in version 12.7.1.

Affected products

• Debian Debian Linux: version 10.0 only
• Fedoraproject Fedora: version 35 only; version 36 only; version 37 only
• Sysstat Project Sysstat: from 9.1.6, before 12.6.1 (fixed in 12.6.1)
