The timed program (in.timed) in UnixWare 7 and OpenUnix 8.0.0 does not properly terminate certain strings with a null, which allows remote attackers to cause a denial of service.
Vulnerability in the passthru driver in SCO UnixWare 7.1.0 allows an attacker to cause a denial of service.
Jolt ICMP attack causes a denial of service in Windows 95 and Windows NT systems.
Oversized ICMP ping packets can result in a denial of service, aka Ping o' Death.
MIME buffer overflow in email clients, e.g. Solaris mailtool and Outlook.
Windows 95/NT out of band (OOB) data denial of service through NETBIOS port, aka WinNuke.
Denial of Service vulnerability in BIND 8 Releases via maliciously formatted DNS messages.
Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.
The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
Inetd in OpenServer 5.0.5 allows remote attackers to cause a denial of service (crash) via a port scan, e.g. with nmap -PO.
Vulnerability in xserver in SCO UnixWare 2.1.x and OpenServer 5.05 and earlier allows an attacker to cause a denial of service which prevents access to reserved port numbers below 1024.
