SB2014011410 - Cryptographic issues in openssl (Alpine package)

Description

This security bulletin contains information about 1 vulnerability.

1) Cryptographic issues (CVE-ID: CVE-2013-6450)

CWE-ID: CWE-310 - Cryptographic Issues

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c.

Remediation

Install update from vendor's website.
