Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Security bypass


Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-7372

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No


The vulnerability allows a renote attacker to bypass security restriction on the target system.

The weakness is due to the use of an incorrect offset value by the engineNextBytes function in Apache Harmony, as used in the Java Cryptography Architecture (JCA) in Android . A remote attacker can leverage the resulting PRNG predictability, defeat cryptographic protection mechanisms and launch further attacks on the system.

Successful exploitation of the vulnerablity results in security bypass on the vulnerable system.


Update to version 4.4.
