Vulnerability ID VCID-2qau-2qt3-aaam
Aliases CVE-2017-9048
Summary Improper Restriction of Operations within the Bounds of a Memory Buffer libxml2 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.
