Synopsis

The remote host is running an outdated version of Adobe Flash Player that is affected by multiple vulnerabilities.

Description

Versions of Adobe Flash Player prior to 11.2.202.635, 18.0.0.375, or 23.0.0.162 are affected by the following vulnerabilities :

 - An unspecified flaw may allow a context-dependent attacker to bypass security restrictions and gain access to potentially sensitive information. No further details have been provided.
 - A use-after-free error may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated when handling AVC decoding. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated when handling SWF data. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A use-after-free condition is triggered when handling 'TextFormat' objects. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
 - An integer overflow condition is triggered as certain input is not properly validated. This may allow a context-dependent attacker to potentially execute arbitrary code.
 - A flaw is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
