TITLE:
Mozilla Firefox Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA36711
VERIFY ADVISORY:
http://secunia.com/advisories/36711/
DESCRIPTION:
Some vulnerabilities have been reported in Mozilla Firefox,
which can
be exploited by malicious people to disclose sensitive
information,
bypass certain security restrictions, manipulate certain data,
or
compromise a user's system.
1) An array indexing error exists when allocating space for
floating
point numbers. This can be exploited to trigger a memory
corruption
when a specially crafted floating point number is processed.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 3.0.14 and 3.5.3.
Prior
versions may also be affected.
2) An error in the form history functionality can be exploited
to
disclose history entries via a specially crafted web page that
triggers the automatic filling of form fields.
3) An error when creating JavaScript web-workers recursively
can be
exploited to trigger the use of freed memory and cause a crash
or
potentially execute arbitrary code.
4) An error exists when parsing regular expressions used in
Proxy
Auto-configuration (PAC). This can be exploited to cause a
crash or
potentially execute arbitrary code via specially crafted
configured
PAC files.
5) An error when processing GIF color maps can be exploited to
cause
a heap-based buffer overflow and potentially execute arbitrary
code
via a specially crafted GIF file.
6) An error in the "XPCVariant::VariantDataToJS()" XPCOM
utility can
be exploited to execute arbitrary JavaScript code with chrome
privileges.
7) An error in the implementation of the JavaScript
"document.getSelection()" function can be exploited to read
text
selected on a web page in a different domain.
8) An error when downloading files can be exploited to display
different file names in the download dialog title bar and
download
dialog body. This can be exploited to obfuscate file names via
a
right-to-left override character and potentially trick a user
into
running an executable file.
9) An error in the embedded liboggz library can be exploited to
cause
a crash or potentially execute arbitrary code.
10) Multiple errors in the embedded libvorbis library can be
exploited to cause crashes or potentially execute arbitrary
code.
11) An error in the embedded liboggplay library can be
exploited to
cause a crash or potentially execute arbitrary code.
12) Multiple errors in the Firefox 3 and Firefox 3.5 browser
engines
can be exploited to cause crashes or potentially execute
arbitrary
code.
13) Multiple errors in the Firefox 3.5 browser engine can be
exploited to cause crashes or potentially execute arbitrary
code.
14) An error in the Firefox 3 browser engine can be exploited
to
cause a crash or potentially execute arbitrary code.
15) Multiple errors in the Firefox 3.5 JavaScript engine can be
exploited to cause crashes or potentially execute arbitrary
code.
SOLUTION:
Update to version 3.0.15 or 3.5.4.
