Security Bulletin
Summary
Security vulnerabilities have been discovered in OpenSSL.
Vulnerability Details
CVE-ID: CVE-2013-4353
DESCRIPTION: A carefully crafted invalid TLS handshake could crash OpenSSL with a NULL pointer exception. A malicious server could use this flaw to crash a connecting client. This issue only affected OpenSSL 1.0.1 versions.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/90201
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2013-6450
DESCRIPTION: A flaw in DTLS handling can cause an application using OpenSSL and DTLS to crash. This is not a vulnerability for OpenSSL prior to 1.0.0. OpenSSL is vulnerable to a denial of service, caused by the failure to properly maintain data structures for digest and encryption contexts by the DTLS retransmission implementation. A remote attacker could exploit this vulnerability to cause the daemon to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/90069
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2013-6449
DESCRIPTION: A flaw in OpenSSL can cause an application using OpenSSL to crash when using TLS version 1.2. This issue only affected OpenSSL 1.0.1 versions.
OpenSSL is vulnerable to a denial of service, caused by an error in the ssl_get_algorithm2 function. A remote attacker could exploit this vulnerability using specially-crafted traffic from a TLS 1.2 client to cause the daemon to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/90068
CVSS Environmental Score*: Undefined
