CVE Descriptions

Use-after-free vulnerability in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 might allow remote attackers to execute arbitrary code via vectors related to incorrect AttributeChildRemoved notifications that affect access to removed nsDOMAttribute child nodes.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-416 Use After Free
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Removal of child nodes from the nsDOMAttribute can allow for a child to still be accessible after removal due to a premature notification of AttributeChildRemoved. Since mFirstChild is not set to NULL until after this call is made, this means the removed child will be accessible after it has been removed. By carefully manipulating the memory layout, this can lead to arbitrary code execution. }, 'License' => MSF_LICENSE, 'Author' => [ 'regenrecht', #vulnerability discovery 'Lincoln<lincoln[at]corelan.be>', #Metasploit module 'corelanc0d3r<peter.ve[at]corelan.be>' #Metasploit module ], 'References' => [ [ 'CVE', '2011-3659' ], [ 'URL', 'http://www.zerodayinitiative.com/advisories/upcoming/'], #ZDI-CAN-1413 [ 'URL', 'https://bugzilla.mozilla.org/show_bug.cgi?id=708198' ] ], 'DefaultOptions' => { 'EXITFUNC' => 'process', 'InitialAutoRunScript' => 'migrate -f' }, 'Payload' => { 'BadChars' => "\x00\x0a\x0d\x34", 'DisableNops' => true, 'PrependEncoder' => "\x81\xc4\x24\xfa\xff\xff" #ADD ESP, -5DC }, 'Platform' => 'win', 'Targets' => [ [ 'Automatic', {} ], [ 'Windows XP -
