Alpine: asterisk: security update to 15.6.2-r0

high Tenable Cloud Security Plugin ID 403575

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x before 15.6.2 and 16.x before 16.0.1
allows remote attackers to crash Asterisk via a specially crafted DNS SRV or NAPTR response, because a
buffer size is supposed to match an expanded length but actually matches a compressed length.
(CVE-2018-19278)

- An Integer Signedness issue (for a return code) in the res_pjsip_sdp_rtp module in Digium Asterisk
versions 15.7.1 and earlier and 16.1.1 and earlier allows remote authenticated users to crash Asterisk via
a specially crafted SDP protocol violation. (CVE-2019-7251)

- Buffer overflow in res_pjsip_messaging in Digium Asterisk versions 13.21-cert3, 13.27.0, 15.7.2, 16.4.0
and earlier allows remote authenticated users to crash Asterisk by sending a specially crafted SIP MESSAGE
message. (CVE-2019-12827)

- An issue was discovered in Asterisk Open Source through 13.27.0, 14.x and 15.x through 15.7.2, and 16.x
through 16.4.0, and Certified Asterisk through 13.21-cert3. A pointer dereference in chan_sip while
handling SDP negotiation allows an attacker to crash Asterisk when handling an SDP answer to an outgoing
T.38 re-invite. To exploit this vulnerability an attacker must cause the chan_sip module to send a T.38
re-invite request to them. Upon receipt, the attacker must send an SDP answer containing both a T.38 UDPTL
stream and another media stream containing only a codec (which is not permitted according to the chan_sip
configuration). (CVE-2019-13161)

- res_pjsip_t38 in Sangoma Asterisk 15.x before 15.7.4 and 16.x before 16.5.1 allows an attacker to trigger
a crash by sending a declined stream in a response to a T.38 re-invite initiated by Asterisk. The crash
occurs because of a NULL session media object dereference. (CVE-2019-15297)
