|Gentoo Linux Security Advisory
Title: OpenSSL: Denial of Service (GLSA 201402-25)
Date: February 21, 2014
A vulnerability in OpenSSL's handling of TLS handshakes could
result in a Denial of Service condition.
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.
Vulnerable: < 1.0.1f
Unaffected: >= 1.0.1f
Unaffected: < 1.0.1
Architectures: All supported architectures
A flaw in the ssl3_take_mac function can result in a NULL pointer
A remote attacker could send a specially crafted TLS handshake,
resulting in a Denial of Service condition.
There is no known workaround at this time.
All OpenSSL 1.0.1 users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1f"
