Debian Security Advisory DSA-3053-1 [email protected]

Package : openssl
CVE ID : CVE-2014-3513 CVE-2014-3566 CVE-2014-3567 CVE-2014-3568
Several vulnerabilities have been found in OpenSSL, the Secure Sockets
Layer library and toolkit.
CVE-2014-3513
A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure
Real-time Transport Protocol (SRTP) extension data. A remote attacker
could send multiple specially crafted handshake messages to exhaust
all available memory of an SSL/TLS or DTLS server.
CVE-2014-3566 ("POODLE")
A flaw was found in the way SSL 3.0 handled padding bytes when
decrypting messages encrypted using block ciphers in cipher block
chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM)
attacker to decrypt a selected byte of a cipher text in as few as 256
tries if they are able to force a victim application to repeatedly send
the same data over newly created SSL 3.0 connections.
This update adds support for Fallback SCSV to mitigate this issue.
CVE-2014-3567
A memory leak flaw was found in the way an OpenSSL handled failed
session ticket integrity checks. A remote attacker could exhaust all
available memory of an SSL/TLS or DTLS server by sending a large number
of invalid session tickets to that server.
CVE-2014-3568
When OpenSSL is configured with "no-ssl3" as a build option, servers
could accept and complete a SSL 3.0 handshake, and clients could be
configured to send them.
For the stable distribution (wheezy), these problems have been fixed in
version 1.0.1e-2+deb7u13.
For the unstable distribution (sid), these problems have been fixed in
version 1.0.1j-1.
We recommend that you upgrade your openssl packages.
