An issue was discovered in Erlang/OTP 18.x. Erlang's generation of compiled regular expressions is vulnerable to a heap overflow. Regular expressions using a malformed extpattern can indirectly specify an offset that is used as an array index. This ordinal permits arbitrary regions within the erts_alloc arena to be both read and written to.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the erlang package has been released.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3571-1 advisory.

    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 Bck, 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)

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

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

This update for erlang fixes security issues and bugs.

The following vulnerabilities were addressed :

  - CVE-2017-1000385: Harden against the Bleichenbacher     attacher against RSA 

  - CVE-2016-10253: Heap overflow through regular     expressions (bsc#1030062)

In addition Erlang was updated to version 18.3.4.6, containing a number of upstream bug fixes and improvements.
