An update that fixes 6 vulnerabilities is now available.
Description:
OpenSSL was updated to fix various security issues.
Following security issues were fixed:
- CVE-2015-0209: A Use After Free following d2i_ECPrivatekey error was
fixed which could lead to crashes for attacker supplied Elliptic Curve
keys. This could be exploited over SSL connections with client supplied
keys.
- CVE-2015-0286: A segmentation fault in ASN1_TYPE_cmp was fixed that
could be exploited by attackers when e.g. client authentication is used.
This could be exploited over SSL connections.
- CVE-2015-0287: A ASN.1 structure reuse memory corruption was fixed. This
problem can not be exploited over regular SSL connections, only if
specific client programs use specific ASN.1 routines.
- CVE-2015-0288: A X509_to_X509_REQ NULL pointer dereference was fixed,
which could lead to crashes. This function is not commonly used, and not
reachable over SSL methods.
- CVE-2015-0289: Several PKCS7 NULL pointer dereferences were fixed, which
could lead to crashes of programs using the PKCS7 APIs. The SSL apis do
not use those by default.
- CVE-2015-0293: Denial of service via reachable assert in SSLv2 servers,
could be used by remote attackers to terminate the server process. Note
that this requires SSLv2 being allowed, which is not the default.
