OpenSSL Bugs

說明

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.

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.
