Package : openssl
CVE ID : CVE-2015-3194 CVE-2015-3195 CVE-2015-3196
Multiple vulnerabilities have been discovered in OpenSSL, a Secure
Sockets Layer toolkit. The Common Vulnerabilities and Exposures project
identifies the following issues:
CVE-2015-3194
Loic Jonas Etienne of Qnective AG discovered that the signature
verification routines will crash with a NULL pointer dereference if
presented with an ASN.1 signature using the RSA PSS algorithm and
absent mask generation function parameter. A remote attacker can
exploit this flaw to crash any certificate verification operation
and mount a denial of service attack.
CVE-2015-3195
Adam Langley of Google/BoringSSL discovered that OpenSSL will leak
memory when presented with a malformed X509_ATTRIBUTE structure.
CVE-2015-3196
A race condition flaw in the handling of PSK identify hints was
discovered, potentially leading to a double free of the identify
hint data.
For the oldstable distribution (wheezy), these problems have been fixed
in version 1.0.1e-2+deb7u18.
For the stable distribution (jessie), these problems have been fixed in
version 1.0.1k-3+deb8u2.
For the unstable distribution (sid), these problems have been fixed in
version 1.0.2e-1 or earlier.
We recommend that you upgrade your openssl packages.
