AIX OpenSSL Advisory : openssl_advisory15.asc

The version of OpenSSL installed on the remote AIX host is affected by multiple vulnerabilities : - A NULL pointer dereference flaw exists in file rsaameth.c when handling ASN.1 signatures that use the RSA PSS algorithm but are missing a mask generation function parameter. A remote attacker can...

Medium: openssl

Issue Overview: A NULL pointer derefernce flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacked could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication. CVE-2015-3194...

Updated openssl packages fix security vulnerability

If a client receives a ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0 then a seg fault can occur leading to a possible denial of service attack CVE-2015-1794. Loic Jonas Etienne of Qnective AG discovered that the signature verification routines will crash with a NU...

openssl lib32-openssl: multiple issues

CVE-2015-3193 insecure private key in connection with DHE There is a carry propagating bug in the x8664 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not...

Vulnerability in OpenSSL - Certificate verify crash with missing PSS parameter

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. Since these routines are used to verify certificate signature algorithms this can be used to crash any...

lib32-openssl: multiple issues

CVE-2015-1787 denial of service If client auth is used then a server can segfault in the event of a DHE ciphersuite being selected and a zero length ClientKeyExchange message being sent by the client. This could be exploited in a DoS attack. - CVE-2015-0207 denial of service The DTLSv1listen...

Vulnerability in OpenSSL - Segmentation fault for invalid PSS parameters

Segmentation fault for invalid PSS parameters. The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and invalid parameters. Since these routines are used to verify certificate signature algorithms this can ...

Internet Bug Bounty: Segmentation fault for invalid PSS parameters

The signature verification routines will crash with a NULL pointer dereference if presented with an ASN.1 signature using the RSA PSS algorithm and invalid parameters. Since these routines are used to verify certificate signature algorithms this can be used to crash any certificate verification...
