Mandriva Linux Security Advisory : mozilla (MDVSA-2012:088-1)

Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Security issues were identified and fixed in mozilla firefox and
thunderbird :

Heap-based buffer overflow in the utf16_to_isolatin1 function in
Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5,
Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and
SeaMonkey before 2.10 allows remote attackers to execute arbitrary
code via vectors that trigger a character-set conversion failure
(CVE-2012-1947)

Use-after-free vulnerability in the nsFrameList::FirstChild function
in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5,
Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and
SeaMonkey before 2.10 allows remote attackers to execute arbitrary
code or cause a denial of service (heap memory corruption and
application crash) by changing the size of a container of absolutely
positioned elements in a column (CVE-2012-1940).

Heap-based buffer overflow in the
nsHTMLReflowState::CalculateHypotheticalBox function in Mozilla
Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird
5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey
before 2.10 allows remote attackers to execute arbitrary code by
resizing a window displaying absolutely positioned and relatively
positioned elements in nested columns (CVE-2012-1941).

Use-after-free vulnerability in the nsINode::ReplaceOrInsertBefore
function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before
10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before
10.0.5, and SeaMonkey before 2.10 might allow remote attackers to
execute arbitrary code via document changes involving replacement or
insertion of a node (CVE-2012-1946).

Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5,
Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and
SeaMonkey before 2.10 allow local users to obtain sensitive
information via an HTML document that loads a shortcut (aka .lnk) file
for display within an IFRAME element, as demonstrated by a network
share implemented by (1) Microsoft Windows or (2) Samba
(CVE-2012-1945).

The Content Security Policy (CSP) implementation in Mozilla Firefox
4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0
through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before
2.10 does not block inline event handlers, which makes it easier for
remote attackers to conduct cross-site scripting (XSS) attacks via a
crafted HTML document (CVE-2012-1944).

Multiple unspecified vulnerabilities in the browser engine in Mozilla
Firefox before 13.0, Thunderbird before 13.0, and SeaMonkey before
2.10 allow remote attackers to cause a denial of service (memory
corruption and application crash) or possibly execute arbitrary code
via vectors related to (1) methodjit/ImmutableSync.cpp, (2) the
JSObject::makeDenseArraySlow function in js/src/jsarray.cpp, and
unknown other components (CVE-2012-1938).

jsinfer.cpp in Mozilla Firefox ESR 10.x before 10.0.5 and Thunderbird
ESR 10.x before 10.0.5 does not properly determine data types, which
allows remote attackers to cause a denial of service (memory
corruption and application crash) or possibly execute arbitrary code
via crafted JavaScript code (CVE-2012-1939).

Multiple unspecified vulnerabilities in the browser engine in Mozilla
Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird
5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey
before 2.10 allow remote attackers to cause a denial of service
(memory corruption and application crash) or possibly execute
arbitrary code via unknown vectors (CVE-2012-1937).

Ken Russell of Google reported a bug in NVIDIA graphics drivers that
they needed to work around in the Chromium WebGL implementation.
Mozilla has done the same in Firefox 13 and ESR 10.0.5
(CVE-2011-3101).

The ASN.1 decoder in the QuickDER decoder in Mozilla Network Security
Services (NSS) before 3.13.4, as used in Firefox 4.x through 12.0,
Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0,
Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10, allows
remote attackers to cause a denial of service (application crash) via
a zero-length item, as demonstrated by (1) a zero-length basic
constraint or (2) a zero-length field in an OCSP response
(CVE-2012-0441). NOTE: This flaw was addressed earlier with the
MDVA-2012:036 advisory.

The mozilla firefox and thunderbird packages has been upgraded to the
latest respective versions which is unaffected by these security
flaws.

Additionally the NSPR and the NSS packages has been upgraded to the
latest versions which resolves various upstream bugs.
