Description:
Some vulnerabilities in PHP4 have been reported, which can be exploited by malicious, local users to bypass certain security restrictions.
1) A boundary error in the "snmpget()" function can be exploited to cause a stack-based buffer overflow via an overly long argument.
2) A double free error exists in the deserialisation of session data, which can be exploited via the "session_decode()" function.
Successful exploitation of these vulnerabilities allows execution of arbitrary code, which can lead to security restrictions, such as the "disable_functions" directive, being bypassed.
The vulnerabilities are reported in version 4.4.6. Other versions may also be affected.
