Gentoo Linux Security Advisory
Title: OpenSSL: Denial of Service (GLSA 200904-08)
Severity: normal
Exploitable: remote
Date: April 07, 2009
Bug(s): #263751
ID: 200904-08
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: dev-libs/openssl
Vulnerable: < 0.9.8k
Unaffected: >= 0.9.8k
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8k" |
