An error in OpenSSL might allow for a Denial of Service when printing certificate details.

Unaffected versions | >= 0.9.8k |
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.
The ASN1_STRING_print_ex() function does not properly check the provided length of a BMPString or UniversalString, leading to an invalid memory access.
A remote attacker could entice a user or automated system to print a specially crafted certificate, possibly leading to a Denial of Service.
There is no known workaround at this time.
All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8k"
