High Nessus Plugin ID 91640

Synopsis

The remote openSUSE host is missing a security update.

Description

This update brings libxml2 to version 2.9.4.

These security issues were fixed :

- CVE-2016-3627: The xmlStringGetNodeList function in tree.c, when used in recovery mode, allowed context-dependent attackers to cause a denial of service (infinite recursion, stack consumption, and application crash) via a crafted XML document (bsc#972335).

- CVE-2016-1833: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1834, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840 (bsc#981108).

- CVE-2016-1835: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document (bsc#981109).

- CVE-2016-1837: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1834, CVE-2016-1836, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840 (bsc#981111).

- CVE-2016-1836: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1834, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840 (bsc#981110).

- CVE-2016-1839: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1834, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, and CVE-2016-1840 (bsc#981114).

- CVE-2016-1838: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1834, CVE-2016-1836, CVE-2016-1837, CVE-2016-1839, and CVE-2016-1840 (bsc#981112).

- CVE-2016-1840: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1834, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, and CVE-2016-1839 (bsc#981115).

- CVE-2016-4483: out-of-bounds read parsing an XML using recover mode (bnc#978395).

- CVE-2016-1834: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document, a different vulnerability than CVE-2016-1833, CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839, and CVE-2016-1840 (bsc#981041).

- CVE-2016-3705: The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 did not properly keep track of the recursion depth, which allowed 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 (bsc#975947).

- CVE-2016-1762: libxml2 allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document (bsc#981040).

This non-security issue was fixed :

- bnc#983288: Fix attribute decoding during XML schema validation

Solution
