CVE-2017-9048

Priority
Medium
Description
libxml2 20904-GITv2.9.4-16-g0741801 is vulnerable to a stack-based buffer
overflow. The function xmlSnprintfElementContent in valid.c is supposed to
recursively dump the element content definition into a char buffer 'buf' of
size 'size'. At the end of the routine, the function may strcat two more
characters without checking whether the current strlen(buf) + 2 < size.
This vulnerability causes programs that use libxml2, such as PHP, to crash.
