The libxml2 library is a development toolbox providing the implementation of various XML standards. A denial of service flaw was found in the way the libxml2 library parsed certain XML files.

    description This upload to Debian squeeze-lts fixes three issues found in the libxml2 package. (1) CVE-2015-1819 / #782782 Florian Weimer from Red Hat reported an issue against libxml2, where a parser which uses libxml2 chokes on a crafted XML document, allocating gigabytes of data. This is a fine line issue between API misuse and a bug in libxml2. This issue got addressed in libxml2 upstream and the patch has been backported to libxml2 in squeeze-lts. (2) #782985 Jun Kokatsu reported an out-of-bounds memory access in libxml2. By entering an unclosed html comment the libxml2 parser didn't stop parsing at the end of the buffer, causing random memory to be included in the parsed comment that was returned to the evoking application. In the Shopify application (where this issue was originally discovered), this caused ruby objects from previous http requests to be disclosed in the rendered page. (3) #783010 Michal Zalewski reported another out-of-bound reads issue in libxml2 that did not cause any crashes but could be detected under ASAN and Valgrind. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An unauthenticated, remote attacker can exploit this, by convincing a user to install a malicious application, to execute arbitrary code with elevated privileges. (CVE-2016-1755) - A flaw exists in libxml2 due to improper validation of user-supplied input while handling XML content. An unauthenticated, remote attacker can exploit this, via a crafted XML document, to cause a denial of service or to execute arbitrary code.

An unauthenticated, remote attacker can exploit this, via a crafted TTF font, to cause a denial or service or to execute arbitrary code. (CVE-2016-1775) - A flaw exists in WebKit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a crafted website, to cause a denial of service or execute arbitrary code. (CVE-2016-1783) - An unspecified flaw exists in the History implementation of WebKit that allows an unauthenticated, remote attacker to cause a denial of service via a crafted website. (CVE-2016-1784) - A heap buffer overflow condition exists in Mozilla Network Security Services due to improper validation of user-supplied input while parsing ASN.1 structures. An unauthenticated, remote attacker can exploit this, via crafted ASN.1 data in an X.509 certificate, to cause a denial of service or execute arbitrary code. (CVE-2016-1950) Note that only 4th generation models are affected by these vulnerabilities, and this plugin only checks these models.

    description Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files.

  • NASL family Amazon Linux Local Security Checks
    NASL id ALA_ALAS-2015-628.NASL
    description A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory. The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data, a different vulnerability than CVE-2015-7941 . 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. A heap-based buffer overflow vulnerability was found in xmlDictComputeFastQKey in dict.c. A heap-based buffer overflow read in xmlParseMisc was found. A heap-based buffer overflow was found in xmlGROW allowing the attacker to read the memory out of bounds. A buffer overread in xmlNextChar was found, causing segmentation fault when compiled with ASAN. Heap-based buffer overflow was found in xmlParseXmlDecl. When conversion failure happens, parser continues to extract more errors which may lead to unexpected behaviour. Stack-based buffer overread vulnerability with HTML parser in push mode in xmlSAX2TextNode causing segmentation fault when compiled with ASAN. A vulnerability in libxml2 was found causing DoS by exhausting CPU when parsing specially crafted XML document. An out-of-bounds heap read in xmlParseXMLDecl happens when a file containing unfinished xml declaration.
