(RSA Issues Fix for RSA BSAFE SSL-C) OpenSSL asn1_d2i_read_bio() Buffer Overflow Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1030012
SecurityTracker URL:  http://securitytracker.com/id/1030012
CVE Reference:   CVE-2012-2110, CVE-2012-2131   (Links to External Site)
Date:  Apr 4 2014
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in OpenSSL. A remote user can execute arbitrary code on the target system. RSA BSAFE SSL-C is affected.

A remote user can send specially crafted data to the target application using OpenSSL to potentially trigger a heap overflow in the asn1_d2i_read_bio() function and execute arbitrary code on the target system. The code will run with the privileges of the target application.

Applications that use ASN.1 BIO or FILE based functions to read untrusted DER format data are affected. The d2i_*_bio and d2i_*_fp type of functions are affected.

Applications that use the memory based ASN1 functions (e.g., d2i_X509, d2i_PKCS12 etc) are not affected.

The SSL/TLS code is not affected.

Applications using only the PEM routines are not affected.

S/MIME and CMS applications that use the built-in MIME parser SMIME_read_PKCS7 and SMIME_read_CMS functions are affected.

Tavis Ormandy, Google Security Team, reported this vulnerability.

Impact:   A remote user can execute arbitrary code on the target system.
Solution:   RSA has issued a fix for RSA BSAFE SSL-C (2.8.9; Advisory ESA-2012-029).
