The SIP channel driver in Asterisk Open Source 1.4.22, 1.4.23, and
1.4.23.1; 1.6.0 before 1.6.0.6; 1.6.1 before 1.6.1.0-rc2; and Asterisk
Business Edition C.2.3, with the pedantic option enabled, allows
remote authenticated users to cause a denial of service (crash) via a
SIP INVITE request without any headers, which triggers a NULL pointer
dereference in the (1) sip_uri_headers_cmp and (2) sip_uri_params_cmp
functions.

CVE-2009-0871 Affects: F9 [bug #489727]

Comment 2 Vincent Danen 2009-03-11 15:30:52 UTC

Fedora 9 and 10 should be updated to 1.6.0.6 which is now available (optionally, a patch to fix the issue is noted on the upstream AST-2009-002 advisory).  For rawhide, 1.6.1.0-rc2 fixes this issue and should be updated.

Comment 3 Fedora Update System 2009-09-25 20:04:47 UTC

asterisk-1.6.0.15-1.fc10 has been pushed to the Fedora 10 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 5 Tomas Hoger 2009-10-27 18:20:17 UTC

Fixed asterisk packages are now in all current Fedora versions.
