A heap-based buffer overflow was found in the __vsyslog_internal

called, or called with the ident argument set to NULL, and the program
name (the basename of argv[0]) is bigger than 1024 bytes, resulting in
an application crash or local privilege escalation. (CVE-2023-6246)
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. (CVE-2023-6779)
An integer 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 very
long message, leading to an incorrect calculation of the buffer size to
store the message, resulting in undefined behavior. (CVE-2023-6780)");
