Description:
Several vulnerabilities were reported in OpenSSL. A remote user can cause denial of service conditions. A remote user can obtain sensitive information. A remote user may be able to execute arbitrary code on the target system.
A remote user can conduct an efficient plaintext recovery attack against the OpenSSL implementation of Datagram Transport Layer Security (DTLS) [CVE-2011-4108, CVE-2012-0390]. Nadhem Alfardan and Kenny Paterson of the Information Security Group at Royal Holloway, University of London (www.isg.rhul.ac.uk) reported this vulnerability.
A remote user can trigger a double-free memory error when a policy check fails [CVE-2011-4109]. Version 0.9.8 systems with the X509_V_FLAG_POLICY_CHECK set are affected. Ben Laurie reported this vulnerability.
The bytes used as block cipher padding in SSL 3.0 records are not cleared. A remote user may be able to conduct a SSL 3.0 handshake to obtain memory contents [CVE-2011-4576]. Adam Langley reported this vulnerability.
Specially crafted RFC 3779 data within a certificate may cause an assertion failure [CVE-2011-4577]. System builds configured with "enable-rfc3779" are affected. Andrew Chi, BBN Technologies, reported this vulnerability.
A remote user can exploit a flaw in handshake restarts for server gated cryptography (SGC) to cause denial of service conditions on the target system [CVE-2011-4619]. Adam Langley reported this vulnerability.
A remote user can send specially crafted GOST parameters to cause the target server to crash [CVE-2012-0027]. OpenSSL GOST ENGINE users are affected. Andrey Kulikov reported this vulnerability.
|
Impact:
A remote user may be able to execute arbitrary code on the target system.
A remote user can cause the target server to crash.
A remote user can obtain plaintext in certain cases.
