"Several vulnerabilities have been discovered in asterisk, an Open
Source PBX and telephony toolkit. The Common Vulnerabilities and
Exposures project identifies the following problems :
- CVE-2009-0041
It is possible to determine valid login names via
probing, due to the IAX2 response from asterisk
(AST-2009-001).
- CVE-2008-3903
It is possible to determine a valid SIP username, when
Digest authentication and authalwaysreject are enabled
(AST-2009-003).
- CVE-2009-3727
It is possible to determine a valid SIP username via
multiple crafted REGISTER messages (AST-2009-008).
- CVE-2008-7220 CVE-2007-2383
It was discovered that asterisk contains an obsolete
copy of the Prototype JavaScript framework, which is
vulnerable to several security issues. This copy is
unused and now removed from asterisk (AST-2009-009).
- CVE-2009-4055
It was discovered that it is possible to perform a
denial of service attack via RTP comfort noise payload
with a long data length (AST-2009-010).
The current version in oldstable is not supported by upstream anymore
and is affected by several security issues. Backporting fixes for
these and any future issues has become unfeasible and therefore we
need to drop our security support for the version in oldstable. We
recommend that all asterisk users upgrade to the stable distribution
(lenny)."
