CVE-2023-34462

A flaw was found in Netty's SniHandler while navigating TLS handshake which may permit a large heap allocation if the handler did not have a timeout configured. This issue may allow an attacker to send a client hello packet which would cause the server to buffer large amounts of data per...

SUSE CVE-2008-0227

yaSSL 1.7.5 and earlier, as used in MySQL and possibly other products, allows remote attackers to cause a denial of service crash via a Hello packet containing a large size value, which triggers a buffer over-read in the HASHwithTransform::Update function in hash.cpp...

CVE-2013-2222

Multiple stack-based buffer overflows in GNU ZRTPCPP before 3.2.0 allow remote attackers to cause a denial of service crash and possibly execute arbitrary code via a crafted ZRTP Hello packet to the 1 ZRtp::findBestSASType, 2 ZRtp::findBestAuthLen, 3 ZRtp::findBestCipher, 4 ZRtp::findBestHash, or...

libzrtpcpp -- multiple security vulnerabilities

Mark Dowd reports: Vulnerability 1. Remote Heap Overflow: If an attacker sends a packet larger than 1024 bytes that gets stored temporarily which occurs many times - such as when sending a ZRTP Hello packet, a heap overflow will occur, leading to potential arbitrary code execution on the vulnerab...

(ospfd): Denial of service by decoding too short Hello packet or Hello packet with invalid OSPFv2 header type

ospfpacket.c in ospfd in Quagga before 0.99.19 allows remote attackers to cause a denial of service daemon crash via 1 a 0x0a type field in an IPv4 packet header or 2 a truncated IPv4 Hello packet...

tls-nextprotoneg NSE Script

Enumerates a TLS server's supported protocols by using the next protocol negotiation extension. This works by adding the next protocol negotiation extension in the client hello packet and parsing the returned server hello's NPN extension data. For more information, see: Script Arguments...

Design/Logic Flaw

The LLTD Mapper in Microsoft Windows Vista does not verify that an IP address in a TLV type 0x07 field in a HELLO packet corresponds to a valid IP address for the local network, which allows remote attackers to trick users into communicating with an external host by sending a HELLO packet with th...

Code injection

The LLTD Mapper in Microsoft Windows Vista allows remote attackers to spoof hosts, and nonexistent bridge relationships, into the network topology map by using a MAC address that differs from the MAC address provided in the Real Source field of the LLTD BASE header of a HELLO packet, aka the "Spo...
