ngeLog-22.214.171.124 Asterisk Project Security Advisory -
AST-2011-002 Product Asterisk Summary Multiple array
overflow and crash vulnerabilities in UDPTL code Nature
of Advisory Exploitable Stack and Heap Array Overflows
Susceptibility Remote Unauthenticated Sessions Severity
Critical Exploits Known No Reported On January 27, 2011
Reported By Matthew Nicholson Posted On February 21,

Matthew Nicholson <mnicholson at digium.com> CVE Name
Description When decoding UDPTL packets, multiple stack
and heap based arrays can be made to overflow by
specially crafted packets. Systems doing T.38 pass
through or termination are vulnerable. Resolution The
UDPTL decoding routines have been modified to respect
the limits of exploitable arrays. In asterisk versions
not containing the fix for this issue, disabling T.38
support will prevent this vulnerability from being
exploited. T.38 support can be disabled in chan_sip by
setting the t38pt_udptl option to 'no' (it is off by
default). t38pt_udptl = no The chan_ooh323 module should
also be disabled by adding the following line in
modles.conf. noload => chan_ooh323 Affected Versions
