(Oracle Issues Fix for Oracle PeopleSoft Products) OpenSSL Bugs Let Users Deny Service and Bypass Authentication in Certain Cases
SecurityTracker Alert ID:  1041893
SecurityTracker URL:  http://securitytracker.com/id/1041893
CVE Reference:   CVE-2018-0739   (Links to External Site)
Date:  Oct 16 2018
Impact:   Denial of service via network, Modification of system information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Two vulnerabilities were reported in OpenSSL. A user can cause denial of service conditions on the target system. A user can bypass authentication in certain cases. Oracle PeopleSoft Products is affected.

A user can create specially crafted ASN.1 data with a recursive definition that, when processed by the target application using the OpenSSL library, will consume excessive stack memory [CVE-2018-0739]. SSL/TLS is not an attack vector.

The PA-RISC CRYPTO_memcmp() function used on HP-UX PA-RISC targets does not properly compare byte values [CVE-2018-0733]. As a result, a user can create forged messages, some of which may be authenticated. The vulnerable module is only compiled by the HP-UX assembler. Version 1.1.0 is affected.

Peter Waltenberg (IBM) reported the CRYPTO_memcmp() vulnerability.
Impact:   A user can cause denial of service conditions.

A user can bypass authentication on the target system in certain cases.
Solution:   Oracle has issued a fix for CVE-2018-0739 for Oracle PeopleSoft Products.
