Patch proposed by the reporter
Scenario (from the openssl-devel report): When I run ./openssl s_server -dtls1 -no_ecdhe -timeout -cert large.pem against ./openssl s_client -dtls1 I'll get a Segmentation fault on the client side. CVE-2009-1379: Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate.

This issue affects openssl version as shipped in Red Hat Enterprise Linux 5 and it will be addressed in the openssl packages update in Red Hat Enterprise Linux 5.4. There is no update planned before than, as both DTLS specification and OpenSSL's implementation is still in development and unlikely to be used in production environments. There is no component shipped in Red Hat Enterprise Linux 5 using OpenSSL's DTLS implementation, except for OpenSSL's testing command line client - openssl. openssl-0.9.8g-14.fc10 has been pushed to the Fedora 10 stable repository. If problems still persist, please make note of it in this bug report. openssl-0.9.8g-9.14.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report. openssl-0.9.8k-5.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report. This issue has been addressed in following products: Red Hat Enterprise Linux 5 Via RHSA-2009:1335 https://rhn.redhat.com/errata/RHSA-2009-1335.html |
