sysstat through 12.7.2 allows a multiplication integer overflow in check_overflow in common.c. NOTE: this issue exists because of an incomplete fix for CVE-2022-39377.

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.

sysstat through 12.2.0 has a double free in check_file_actlst in sa_common.c.

sysstat before 12.1.6 has memory corruption due to an Integer Overflow in remap_struct() in sa_common.c.

An issue was discovered in sysstat 12.1.1. The remap_struct function in sa_common.c has an out-of-bounds read during a memset call, as demonstrated by sadf.
