SCO : Security Vulnerabilities, CVEs, CVSS score between 3 and 5.99

Directory traversal vulnerability in (1) pkgadd and (2) pkgrm in SCO UnixWare 7.1.4 allows local users to gain privileges via unknown vectors.

Buffer overflow in the Strcmp function in the XKEYBOARD extension in X Window System X11R6.4 and earlier, as used in SCO UnixWare 7.1.3 and Sun Solaris 8 through 10, allows local users to gain privileges via a long _XKB_CHARSET environment variable value.

Buffer overflow in uidadmin in SCO Unixware 7.1.3 and 7.1.4 allows local users to execute arbitrary code via a -S (scheme) argument that specifies a large file, a different vulnerability than CVE-2001-1063.

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 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.

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.

The X server in SCO UnixWare 7.1.1, 7.1.3, and 7.1.4 does not properly create socket directories in /tmp, which could allow attackers to hijack local sockets.

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.

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.

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.

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.

SCO UnixWare 7.1.1, 7.1.3, and Open UNIX 8.0.0 allows local users to bypass protections for the "as" address space file for a process ID (PID) by obtaining a procfs file descriptor for the file and calling execve() on a setuid or setgid program, which leaves the descriptor open to the user.

ISC BIND 8.3.x before 8.3.7, and 8.4.x before 8.4.3, allows remote attackers to poison the cache via a malicious name server that returns negative responses with a large TTL (time-to-live) value.

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.

Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.

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.

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.

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.

Multiple buffer overflows in programs used by scoadmin and sysadmsh in SCO OpenServer 5.0.6a and earlier allow local users to gain privileges via a long TERM environment variable to (1) atcronsh, (2) auditsh, (3) authsh, (4) backupsh, (5) lpsh, (6) sysadm.menu, or (7) termsh.

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.

vi as included with SCO OpenServer 5.0 - 5.0.6 allows a local attacker to overwrite arbitrary files via a symlink attack.

sendmail 8.9.3, as included with the MMDF 2.43.3b package 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.
