VCID-2qau-2qt3-aaam Aliases: CVE-2017-9048	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.	There are no reported fixed by versions.
VCID-46k1-2uqz-aaab Aliases: CVE-2017-9047	Improper Restriction of Operations within the Bounds of a Memory Buffer A buffer overflow was discovered in libxml2 . The function xmlSnprintfElementContent in valid.c is supposed to recursively dump the element content definition into a char buffer 'buf' of size 'size'. The variable len is assigned strlen(buf). If the content->type is XML_ELEMENT_CONTENT_ELEMENT, then (i) the content->prefix is appended to buf (if it actually fits) whereupon (ii) content->name is written to the buffer. However, the check for whether the content->name actually fits also uses 'len' rather than the updated buffer length strlen(buf). This allows us to write about "size" many bytes beyond the allocated memory. This vulnerability causes programs that use libxml2, such as PHP, to crash.	There are no reported fixed by versions.
VCID-4kts-b8nu-aaad Aliases: CVE-2017-9050 GHSA-8c56-cpmw-89x7	Out-of-bounds read in nokogiri	There are no reported fixed by versions.
VCID-9xpa-dx6k-aaap Aliases: CVE-2017-9049	Out-of-bounds Read libxml2 is vulnerable to a heap-based buffer over-read in the xmlDictComputeFastKey function in dict.c. This vulnerability causes programs that use libxml2, such as PHP, to crash.	There are no reported fixed by versions.
VCID-d41f-qy2v-aaan Aliases: CVE-2017-8872	Out-of-bounds Read The htmlParseTryOrFinish function in HTMLparser.c in libxml2 allows attackers to cause a denial of service (buffer over-read) or information disclosure.	There are no reported fixed by versions.
VCID-d7ye-gyq7-aaad Aliases: CVE-2017-7375	Improper Restriction of XML External Entity Reference A flaw in libxml2 allows remote XML entity inclusion with default parser flags (i.e., when the caller did not request entity substitution, DTD validation, external DTD subset loading, or default DTD attributes). Depending on the context, this may expose a higher-risk attack surface in libxml2 not usually reachable with default parser flags, and expose content from local files, HTTP, or FTP servers (which might be otherwise unreachable).	There are no reported fixed by versions.
VCID-e47u-5zh7-aaad Aliases: CVE-2016-9318	libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document.	There are no reported fixed by versions.
VCID-pf6b-dxvk-aaan Aliases: CVE-2016-5131	Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.	There are no reported fixed by versions.
VCID-th6j-c7js-aaaf Aliases: CVE-2017-16932 GHSA-x2fm-93ww-ggvx	parser.c in libxml2 before 2.9.5 does not prevent infinite recursion in parameter entities.	There are no reported fixed by versions.
VCID-w7vw-1nq3-aaac Aliases: CVE-2016-1838	Out-of-bounds Read The xmlPArserPrintFileContextInternal function in libxml2, as used in Apple iOS, OS X, tvOS, and watchOS, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.	There are no reported fixed by versions.
VCID-zqqw-fe14-aaac Aliases: CVE-2017-16931	parser.c in libxml2 before 2.9.5 mishandles parameter-entity references because the NEXTL macro calls the xmlParserHandlePEReference function in the case of a '%' character in a DTD name.	There are no reported fixed by versions.

At the end of the routine, the function may strcat two more characters without checking whether the current strlen(buf) + 2 < size.
