*	syslog: Fix heap buffer overflow in __vsyslog_internal (CVE-2023-6246)	Arjun Shankar	2024-01-30	1	-0/+39
	__vsyslog_internal did not handle a case where printing a SYSLOG_HEADER containing a long program name failed to update the required buffer size, leading to the allocation and overflow of a too-small buffer on the heap. This commit fixes that. It also adds a new regression test that uses glibc.malloc.check.
