Amazon Linux 2 : libsrtp (ALAS-2020-1530)

high Nessus Plugin ID 141941

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of libsrtp installed on the remote host is prior to 1.4.4-11.20101004cvs. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1530 advisory.

 Buffer overflow in srtp.c in libsrtp in srtp 1.4.5 and earlier allows remote attackers to cause a denial of service (crash) via vectors related to a length inconsistency in the crypto_policy_set_from_profile_for_rtp and srtp_protect functions. (CVE-2013-2139)

 The encryption-processing feature in Cisco libSRTP before 1.5.3 allows remote attackers to cause a denial of service via crafted fields in SRTP packets, aka Bug ID CSCux00686. (CVE-2015-6360)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update libsrtp' to update your system.
