Ubuntu Security Notice USN-3571-1

14th February, 2018

erlang vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

    Ubuntu 17.10
    Ubuntu 16.04 LTS
    Ubuntu 14.04 LTS

Summary

Several security issues were fixed in Erlang.

Software description

    erlang - Concurrent, real-time, distributed functional language

Details

It was discovered that the Erlang FTP module incorrectly handled certain
CRLF sequences. A remote attacker could possibly use this issue to inject
arbitrary FTP commands. This issue only affected Ubuntu 14.04 LTS.
(CVE-2014-1693)

It was discovered that Erlang incorrectly checked CBC padding bytes. A
remote attacker could possibly use this issue to perform a padding oracle
attack and decrypt traffic. This issue only affected Ubuntu 14.04 LTS.
(CVE-2015-2774)

It was discovered that Erlang incorrectly handled certain regular
expressions. A remote attacker could possibly use this issue to cause
Erlang to crash, resulting in a denial of service, or execute arbitrary
code. This issue only affected Ubuntu 16.04 LTS. (CVE-2016-10253)

Hanno Böck, Juraj Somorovsky and Craig Young discovered that the Erlang
otp TLS server incorrectly handled error reporting. A remote attacker could
possibly use this issue to perform a variation of the Bleichenbacher attack
and decrypt traffic or sign messages. (CVE-2017-1000385)
