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.
