An update that solves 12 vulnerabilities and has one errata

is now available.

 

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).
