CVE-2011-0495 [MEDIUM] CVE-2011-0495 Asterisk: Stack-based buffer overflow by forming an outgoing SIP request with specially-crafted caller ID information (AST-2011-001)
CVE-2011-0495 Asterisk: Stack-based buffer overflow by forming an outgoing SIP request with specially-crafted caller ID information (AST-2011-001)
A stack-based buffer overflow was found in the way Asterisk,
an open source telephony toolkit, encoded text strings to
their URI-encoded version, when forming an outgoing SIP
request. A remote, authenticated attacker could use this
flaw to cause asterisk daemon to crash (denial of service) or,
potentially, execute arbitrary code with the privileges of
the user running asterisk via a specially-crafted caller
ID information provided to Asterisk's URIs encoding routine.
