Some vulnerabilities have been reported in Adobe Flash Player, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, or to potentially compromise a user's system. 1) A boundary error exists in the processing of "Declare Function (V7)" tags. This can be exploited to cause a heap-based buffer overflow via specially crafted flags. 2) An integer overflow in the processing of multimedia files can be exploited to cause a buffer overflow. Successful exploitation of the vulnerabilities may allow execution of arbitrary code. 3) Errors when pinning a hostname to an IP address can be exploited to conduct DNS rebinding attacks. This is related to vulnerability #3 in:
SA28161 4) An error when sending HTTP headers can be exploited to bypass cross-domain policy files. 5) An error exists in the enforcing of cross-domain policy files.
