CVE-2009-1377

Status Candidate

Overview

The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of "future epoch" DTLS records that are buffered in a queue, aka "DTLS record buffer limitation bug."

Ubuntu Security Notice 792-1
Posted Jun 25, 2009
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice USN-792-1 - It was discovered that OpenSSL did not limit the number of DTLS records it would buffer when they arrived with a future epoch. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. It was discovered that OpenSSL did not properly free memory when processing DTLS fragments. A remote attacker could cause a denial of service via memory resource consumption by sending a large number of crafted requests. It was discovered that OpenSSL did not properly handle certain server certificates when processing DTLS packets. A remote DTLS server could cause a denial of service by sending a message containing a specially crafted server certificate. It was discovered that OpenSSL did not properly handle a DTLS ChangeCipherSpec packet when it occurred before ClientHello. A remote attacker could cause a denial of service by sending a specially crafted request. It was discovered that OpenSSL did not properly handle out of sequence DTLS handshake messages. A remote attacker could cause a denial of service by sending a specially crafted request.

The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of future epoch DTLS records that are buffered in a queue, aka DTLS record buffer limitation bug. Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka DTLS fragment handling memory leak. The updated packages have been patched to prevent this.
