CVE-2023-6779

An off-by-one heap-based buffer overflow was found in the
__vsyslog_internal 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 message bigger than INT_MAX bytes, leading to an
incorrect calculation of the buffer size to store the message, resulting in
an application crash. This issue affects glibc 2.37 and newer.
