Package : openssl
CVE ID : CVE-2015-0209 CVE-2015-0286 CVE-2015-0287 CVE-2015-0288
CVE-2015-0289 CVE-2015-0292
Debian Bug : 781081
The openssl update issued as DSA 3197-1 caused regressions. This update
reverts the defective patch applied in that update causing these
problems. Additionally a follow-up fix for CVE-2015-0209 is applied.
For reference the original advisory text follows.
Multiple vulnerabilities have been discovered in OpenSSL, a Secure
Sockets Layer toolkit. The Common Vulnerabilities and Exposures project
identifies the following issues:
CVE-2015-0286
Stephen Henson discovered that the ASN1_TYPE_cmp() function
can be crashed, resulting in denial of service.
CVE-2015-0287
Emilia Kaesper discovered a memory corruption in ASN.1 parsing.
CVE-2015-0289
Michal Zalewski discovered a NULL pointer dereference in the
PKCS#7 parsing code, resulting in denial of service.
CVE-2015-0292
It was discovered that missing input sanitising in base64 decoding
might result in memory corruption.
CVE-2015-0209
It was discovered that a malformed EC private key might result in
memory corruption.
CVE-2015-0288
It was discovered that missing input sanitising in the
X509_to_X509_REQ() function might result in denial of service.
For the stable distribution (wheezy), these problems have been fixed in
version 1.0.1e-2+deb7u16.
We recommend that you upgrade your openssl packages.
