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.

mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials.

Buffer overflow in termsh on SCO OpenServer 5.0.7 allows remote attackers to execute arbitrary code via a long -o command line argument. NOTE: this is probably a different vulnerability than CVE-2005-0351 since it involves a distinct attack vector.

SCO OpenServer 5.0.5 through 5.0.7 only supports Xauthority style access control when users log in using scologin, which allows remote attackers to gain unauthorized access to an X session via other X login methods.

lpadmin in SCO OpenServer 5.0.6 can allow a local attacker to gain additional privileges via a buffer overflow attack in the first argument to the command.

FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce.

Buffer overflow in MMDF server allows remote attackers to gain privileges via a long MAIL FROM command to the SMTP daemon.

Vulnerability in (1) rlogin daemon rshd and (2) scheme on SCO UNIX OpenServer 5.0.5 and earlier, and SCO UnixWare 7.0.1 and earlier, allows remote attackers to gain privileges.

Multiple buffer overflows in MMDF on OpenServer 5.0.6 and 5.0.7, and possibly other operating systems, may allow attackers to execute arbitrary code, as demonstrated via the execmail program.

Buffer overflow in mscreen on SCO OpenServer 5.0 and SCO UNIX 3.2v4 allows a local user to gain root access via (1) a long TERM environmental variable and (2) a long entry in the .mscreenrc file.

Buffer overflow in SCO mscreen allows local users to gain root privileges via a long terminal entry (TERM) in the .mscreenrc file.

recon in SCO OpenServer 5.0 through 5.0.6 can allow a local attacker to gain additional privileges via a buffer overflow attack in the first command line argument.

Local user gains root privileges via buffer overflow in rdist, via lookup() function.

Command execution in Sun systems via buffer overflow in the at program.

Buffer overflow and denial of service in Sendmail 8.7.5 and earlier through GECOS field gives root access to local users.

deliver program in MMDF 2.43.3b in SCO OpenServer 5.0.6 can allow a local attacker to gain additional privileges via a buffer overflow in the first argument to the command.

Multiple buffer overflows in the enable command for SCO OpenServer 5.0.6 and 5.0.7 allow local users to execute arbitrary code via long command line arguments.

Buffer overflow in sar for SCO OpenServer 5.0.0 through 5.0.5 may allow local users to gain root privileges via a long -f parameter, a different vulnerability than CVE-1999-1570.

SCO Internet Manager (mana) allows local users to execute arbitrary programs by setting the REMOTE_ADDR environment variable to cause menu.mana to run as if it were called from ncsa_httpd, then modifying the PATH environment variable to point to a malicious "hostname" program.

Several startup scripts in SCO OpenServer Enterprise System v 5.0.4p, including S84rpcinit, S95nis, S85tcp, and S89nfs, are vulnerable to a symlink attack, allowing a local user to gain root access.

Vulnerability in scoterm in SCO OpenServer 5.0 and SCO Open Desktop/Open Server 3.0 allows local users to gain root privileges.

Vulnerability in a kernel error handling routine in SCO OpenServer 5.0.2 and earlier, and SCO Internet FastStart 1.0, allows local users to gain root privileges.

The scosession program in OpenServer 5.0.6 and 5.0.7 allows local users to gain privileges via crafted strings on the commandline.

Format string vulnerability in crontab for SCO OpenServer 5.0.5 and 5.0.6 allows local users to gain privileges via format string specifiers in the file name argument.

Unknown vulnerability in display of Merge before 5.3.23a in UnixWare 7.1.x allows local users to gain root privileges.

SCO Doctor allows local users to gain root privileges through a Tools option.

A weak encryption algorithm is used for passwords in SCO TermVision, allowing them to be easily decrypted by a local user.

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.

Oversized ICMP ping packets can result in a denial of service, aka Ping o' Death.

Windows 95/NT out of band (OOB) data denial of service through NETBIOS port, aka WinNuke.

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.
