CVE-2014-8176
Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that an invalid memory free could be triggered when buffering DTLS data. This could allow remote attackers to cause a denial of service (crash) or potentially execute arbitrary code. This issue only affected the oldstable distribution (wheezy).
CVE-2015-1788
Joseph Barr-Pixton discovered that an infinite loop could be triggered due to incorrect handling of malformed ECParameters structures. This could allow remote attackers to cause a denial of service.
CVE-2015-1789
Robert Swiecki and Hanno Bock discovered that the X509_cmp_time function could read a few bytes out of bounds. This could allow remote attackers to cause a denial of service (crash) via crafted certificates and CRLs.
CVE-2015-1790
Michal Zalewski discovered that the PKCS#7 parsing code did not properly handle missing content which could lead to a NULL pointer dereference. This could allow remote attackers to cause a denial of service (crash) via crafted ASN.1-encoded PKCS#7 blobs.
CVE-2015-1791
Emilia Kasper discovered that a race condition could occur due to incorrect handling of NewSessionTicket in a multi-threaded client, leading to a double free. This could allow remote attackers to cause a denial of service (crash).
CVE-2015-1792
Johannes Bauer discovered that the CMS code could enter an infinite loop when verifying a signedData message, if presented with an unknown hash function OID. This could allow remote attackers to cause a denial of service.
Additionally OpenSSL will now reject handshakes using DH parameters shorter than 768 bits as a countermeasure against the Logjam attack (CVE-2015-4000).
For the oldstable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u17.
For the stable distribution (jessie), these problems have been fixed in version 1.0.1k-3+deb8u1.
For the testing distribution (stretch), these problems have been fixed in version 1.0.2b-1.
For the unstable distribution (sid), these problems have been fixed in version 1.0.2b-1.
We recommend that you upgrade your openssl packages.");
