Title:	Mageia: Security Advisory (MGASA-2014-0171)
Summary:	The remote host is missing an update for the 'asterisk' package(s) announced via the MGASA-2014-0171 advisory.
Description:	Summary: The remote host is missing an update for the 'asterisk' package(s) announced via the MGASA-2014-0171 advisory. Vulnerability Insight: Updated asterisk packages fix security vulnerabilities: In Asterisk before 11.6.1, a 16 bit SMS message that contains an odd message length value will cause the message decoding loop to run forever. The message buffer is not on the stack but will be overflowed resulting in corrupted memory and an immediate crash (CVE-2013-7100). In Asterisk before 11.6.1, external control protocols, such as the Asterisk Manager Interface, often have the ability to get and set channel variables, this allows the execution of dialplan functions. Reading the SHELL() function can execute arbitrary commands on the system Asterisk is running on. Writing to the FILE() function can change any file that Asterisk has write access to. When these functions are executed from an external protocol, that execution could result in a privilege escalation (AST-2013-007). In Asterisk before 11.8.1, sending a HTTP request that is handled by Asterisk with a large number of Cookie headers could overflow the stack. You could even exhaust memory if you sent an unlimited number of headers in the request (CVE-2014-2286). In Asterisk before 11.8.1, an attacker can use all available file descriptors using SIP INVITE requests. Each INVITE meeting certain conditions will leak a channel and several file descriptors. The file descriptors cannot be released without restarting Asterisk which may allow intrusion detection systems to be bypassed by sending the requests slowly (CVE-2014-2287). Affected Software/OS: 'asterisk' package(s) on Mageia 3. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
