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 tested product installed on the remote host is prior to tested version. 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)

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

Solution

Run 'yum update libsrtp' to update your system.
