Synopsis
========
An error in OpenSSL might allow for a Denial of Service when printing
certificate details.
Background
==========
OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
purpose cryptography library.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/openssl < 0.9.8k >= 0.9.8k
Description
===========
The ASN1_STRING_print_ex() function does not properly check the
provided length of a BMPString or UniversalString, leading to an
invalid memory access.
Impact
======
A remote attacker could entice a user or automated system to print a
specially crafted certificate, possibly leading to a Denial of Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All OpenSSL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8k"
References
==========
