Vulnerabilidades

A reflected Cross-site scripting (XSS) vulnerability in Xinuo (formerly SCO) Openserver version 5 and 6 allows remote attackers to inject arbitrary web script or HTML tag via the parameter 'section'.

Xinuos (formerly SCO) Openserver v5 and v6 allows attackers to execute arbitrary commands via shell metacharacters in outputform or toclevels parameter to cgi-bin/printbook.

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.

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 CCITTFaxDecode stream, which lead to integer overflows and integer underflows.

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.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

Stack-based buffer overflow in (1) backupsh and (2) authsh in SCO Openserver 5.0.7 allows local users to execute arbitrary code via a long HOME environment variable.

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 execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack…

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

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, which causes inetd to launch a separate process for each request.

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 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.

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 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.

TCP, when using a large Window Size, makes it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP.

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.

Docview before 1.1-18 in Caldera OpenLinux 3.1.1, SCO Linux 4.0, OpenServer 5.0.7, configures the Apache web server in a way that allows remote attackers to read arbitrary publicly readable files via a certain URL, possibly related to rewrite rules.
