UBUNTU-CVE-2014-3507

Memory leak in d1both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service memory consumption via zero-length DTLS fragments that trigger improper handling of the return value of a certain...

UBUNTU-CVE-2014-3505

Double free vulnerability in d1both.c in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote attackers to cause a denial of service application crash via crafted DTLS packets that trigger an error condition...

openssl: DoS when sending invalid DTLS handshake

A denial of service flaw was found in the way OpenSSL handled certain DTLS ServerHello requests. A specially crafted DTLS handshake packet could cause a DTLS client using OpenSSL to crash...

openssl: Buffer overflow via DTLS invalid fragment

The dtls1reassemblefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service buffer overflow a...

DEBIAN-CVE-2014-0195

The dtls1reassemblefragment function in d1both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly validate fragment lengths in DTLS ClientHello messages, which allows remote attackers to execute arbitrary code or cause a denial of service buffer overflow a...

UBUNTU-CVE-2013-1586

The fragmentsettotlen function in epan/reassemble.c in Wireshark 1.6.x before 1.6.13 and 1.8.x before 1.8.5 does not properly determine the length of a reassembled packet for the DTLS dissector, which allows remote attackers to cause a denial of service application crash via a malformed packet...

openssl: DTLS plaintext recovery attack

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack...
