CVE-2014-3508

Name of the Vulnerable Software and Affected Versions OpenSSL versions 0.9.8 through 0.9.8zb OpenSSL versions 1.0.0 through 1.0.0n OpenSSL versions 1.0.1 through 1.0.1i

Description The issue arises from the OBJ obj2txt function in OpenSSL when pretty printing is used, as it does not ensure the presence of '0' characters. This allows context-dependent attackers to obtain sensitive information from process stack memory by reading output from functions such as X509 name oneline and X509 name print ex.

Recommendations For OpenSSL versions 0.9.8 through 0.9.8zb, update to version 0.9.8zb or later. For OpenSSL versions 1.0.0 through 1.0.0n, update to version 1.0.0n or later. For OpenSSL versions 1.0.1 through 1.0.1i, update to version 1.0.1i or later. As a temporary workaround, consider disabling pretty printing in the OBJ obj2txt function until a patch is available.
