CVE-2017-9048 medium priority: Ubuntu including 1 source packages (libxml2), 5 status rows across 5 suites (trusty, upstream, xenial, yakkety, zesty): released 4, ignored 1.
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.
