glibc: Integer overflow in memalign leads to heap corruption

A flaw was found in the glibc library. Passing an excessively large alignment value to the memalign suite of functions, such as memalign, posixmemalign, alignedalloc, valloc and pvalloc, an integer overflow can occur during internal size calculations due to improper overflow checks, causing an...

Siemens SIMATIC S7-1500 Incorrect Calculation of Buffer Size (CVE-2023-6780)

An integer overflow was found in the vsysloginternal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a very long message, leading to an incorrect calculation of the buffer size to store the message,...
