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…

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a…

Buffer overflow in nwprint in SCO OpenServer 5.0.7 allows local users to execute arbitrary code via a long command line argument.

Buffer overflow in (1) termsh, (2) atcronsh, and (3) auditsh in SCO OpenServer 5.0.6 and 5.0.7 might allow local users to execute arbitrary code via a long HOME environment variable.

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…

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.

The NFS mountd service on SCO UnixWare 7.1.1, 7.1.3, 7.1.4, and 7.0.1, and possibly other versions, when run from inetd, allows remote attackers to cause a denial of service (memory exhaustion) via a series of requests,…

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.

Multiple unknown vulnerabilities in MMDF on OpenServer 5.0.6 and 5.0.7, and possibly other operating systems, may allow attackers to cause a denial of service by triggering a core dump.

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.

Multiple unknown vulnerabilities in MMDF on OpenServer 5.0.6 and 5.0.7, and possibly other operating systems, may allow attackers to cause a denial of service by triggering 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.

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…

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.

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.

Unknown vulnerability in chroot on SCO UnixWare 7.1.1 through 7.1.4 allows local users to escape the chroot jail and conduct unauthorized activities.

Certain scripts in OpenServer before 5.0.6 allow local users to overwrite files and conduct other unauthorized activities via a symlink attack on temporary files.

The Script.prototype.freeze/thaw functionality in Mozilla 1.4 and earlier allows attackers to execute native methods by modifying the string used as input to the script.thaw JavaScript function, which is then…

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…

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

The getdbm procedure in ypxfrd allows local users to read arbitrary files, and remote attackers to read databases outside /var/yp, via a directory traversal and symlink attack on the domain and map arguments.

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 SCO OpenServer 5.0.6 and earlier allows local users to modify critical information such as certain CPU registers and segment descriptors.

Buffer overflow in lpstat in SCO OpenServer 5.0 through 5.0.6a allows local users to execute arbitrary code as group bin via a long command line argument.

Buffer overflow in login in various System V based operating systems allows remote attackers to execute arbitrary commands via a large number of arguments through services such as telnet and rlogin.

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.

Buffer overflow in lpforms in SCO OpenServer 5.0-5.0.6 can allow a local attacker to gain additional privileges via a long first argument to the lpforms command.
