SecurityTracker Alert ID:  1036668
SecurityTracker URL:  http://securitytracker.com/id/1036668
CVE Reference:   CVE-2015-1794, CVE-2015-3195   (Links to External Site)
Date:  Aug 19 2016
Impact:   Denial of service via network, Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 5.0.X, 5.1.X, 6.0.13 and prior, 6.1.12 and prior, 7.0.8 and prior, 7.1.3 and prior
Description:   Multiple vulnerabilities were reported in OpenSSL. A remote user can cause the target service to crash. A remote user can obtain potentially sensitive information on the target system. Palo Alto PAN-OS is affected.

A remote server can send a specially crafted ServerKeyExchange for an anonymous DH ciphersuite with the value of p set to 0 to potentially cause the target service to crash [CVE-2015-1794]. Version 1.0.2 is affected.

The vendor was notified on August 3, 2015.

Guy Leaver (Cisco) reported this vulnerability.

A remote user can exploit a carry propagation flaw in BN_mod_exp() to potentially determine information about the private key in certain situations [CVE-2015-3193].

Systems configured for persistent DH parameters and sharing a private key between multiple clients are affected. Version 1.0.2 is affected.

The vendor was notified on August 13, 2015.

Hanno Bock reported this vulnerability.

A remote user can send a certificate with a specially crafted ASN.1 signature that uses the RSA PSS algorithm and does not contain the mast generation function parameter to trigger a null pointer dereference and crash [CVE-2015-3194]. Versions 1.0.1 and 1.0.2 are affected.

The vendor was notified on August 27 2015.

Loic Jonas Etienne (Qnective AG) reported this vulnerability.

A remote user can supply a specially crafted X509_ATTRIBUTE structure to trigger a memory leak and potentially disclose sensitive information [CVE-2015-3195]. Applications that read PKCS#7 or CMS data from untrusted sources are affected. SSL/TLS is not affected.

The vendor was notified on November 9, 2015.

Adam Langley (Google/BoringSSL) reported this vulnerability.

A remote user can send send PSK identity hints to a multi-threaded client to trigger a race condition and then a double free memory error and cause the target service to crash [CVE-2015-3196]. Versions 1.0.0, 1.0.1 (prior to 1.0.1p), and 1.0.2 (prior to 1.0.2d) are affected.

Impact:   A remote user can cause the target service to crash.

A remote user can obtain potentially sensitive information on the target system.

Solution:   Palo Alto Networks has issued a fix for CVE-2015-1794 and CVE-2015-3195 for Palo Alto PAN-OS (6.0.14, 6.1.13, 7.0.9, 7.1.4).
