Hi, the following vulnerability was published for libxml2. CVE-2017-9048[0]: | 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. The report at [1] mentions that this was reported upstream as [2], but the upstream bug report is not yet opened. The posting at [1] contains a patch which is not yet blessed upstream. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
