CVE-2017-5969 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
libxml2 2.9.4, when used in recover mode, allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted XML document. NOTE: The maintainer states "I would disagree of a CVE with the Recover parsing option which should only be used for manual recovery at least for XML parser.
CVE-2017-9047 2 Redhat, Xmlsoft 2 Jboss Core Services, Libxml2 2025-04-20 N/A
A buffer overflow was discovered in libxml2 20904-GITv2.9.4-16-g0741801. 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.
CVE-2015-9019 1 Xmlsoft 1 Libxslt 2025-04-20 N/A
In libxslt 1.1.29 and earlier, the EXSLT math.random function was not initialized with a random seed during startup, which could cause usage of this function to produce predictable outputs.
CVE-2017-16931 1 Xmlsoft 1 Libxml2 2025-04-20 N/A
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.
CVE-2015-7941 3 Canonical, Redhat, Xmlsoft 4 Ubuntu Linux, Enterprise Linux, Jboss Enterprise Web Server and 1 more 2025-04-12 N/A
libxml2 2.9.2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted XML data to the (1) xmlParseEntityDecl or (2) xmlParseConditionalSections function in parser.c, as demonstrated by non-terminated entities.
CVE-2015-6838 3 Php, Redhat, Xmlsoft 3 Php, Rhel Software Collections, Libxml2 2025-04-12 N/A

The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data.
CVE-2015-8317 5 Canonical, Debian, Hp and 2 more 11 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 8 more 2025-04-12 N/A
The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
CVE-2016-3705 6 Canonical, Debian, Hp and 3 more 8 Ubuntu Linux, Debian Linux, Icewall Federation Agent and 5 more 2025-04-12 N/A
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references.
CVE-2016-1684 3 Google, Redhat, Xmlsoft 3 Chrome, Rhel Extras, Libxslt 2025-04-12 N/A
numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles the i format token for xsl:number data, which allows remote attackers to cause a denial of service (integer overflow or resource consumption) or possibly have unspecified other impact via a crafted document.
