An arithmetic overflow issue was discovered in Sysstat on 32-bit systems. The allocate_structures() function in sa_common.c insufficiently checks bounds before arithmetic multiplication, allowing an overflow in the size allocated for the buffer representing system activities. The vulnerability can be triggered when displaying activity data files and may lead to memory corruption or possibly arbitrary code execution due to an incorrectly sized buffer.
