NULL pointer dereference in X509 parsing (CVE-2015-0288) NULL pointer derererence in elliptic curves (CVE-2015-0209)
Handshake with unseeded PRNG (CVE-2015-0285)
Cherrypicked from errata4.0-0 (==ucs4.0-1) to errata4.0-1 CVE-2015-0285 does not apply to 1.0.1e, introduced later via upstream git commit 173e72e64c6a07ae97660c322396b66215009f33 (Mon Mar 11 15:34:28 2013) Advisory: 2015-03-18-openssl.yaml

Additional issues: Denial of service during certificate signature algorithm verification in ASN1_TYPE_cmp function (CVE-2015-0286) Memory corruption in ASN.1 parsing. Only affects applications with rarely found strongly discouraged ASN.1 parsing flaw (CVE-2015-0287) Denial of service due to NULL pointer dereference in the PKCS#7 parsing code. Quote: "Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected." (CVE-2015-0289) Memory corruption due to missing input sanitising in base64 decoding. Could be exploited by maliciously crafted base64 data. Quote: "Any code path that reads base64 data from an untrusted source could be affected (such as the PEM processing routines). (CVE-2015-0292)
Updated upstream wheezy package imported and built in errata4.0-1. Advisory is updated.

There's been a regression update in Debian, we should incorporate that update: https://lists.debian.org/debian-security-announce/2015/msg00090.html
(In reply to Moritz Muehlenhoff from comment #7) > There's been a regression update in Debian, we should incorporate that > update: > https://lists.debian.org/debian-security-announce/2015/msg00090.html The version in 3.2 is ok, the faulty patch isn't present there.
The update package has been built. YAML also updated.
