The STARTTLS implementation in SCO SCOoffice Server does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted SMTP sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

Unspecified vulnerability in the IGMP driver in SCO Unixware Release 7.1.4 Maintenance Pack 4 allows attackers to cause a denial of service (system panic) via unspecified vectors.

Merge mcd in ReliantHA 1.1.4 in SCO UnixWare 7.1.4 allows local users to gain root privileges via a crafted -d argument that contains .. (dot dot) sequences that point to a directory containing a file whose name includes shell metacharacters.

Untrusted search path vulnerability in (1) hvdisp and (2) rcvm in ReliantHA 1.1.4 in SCO UnixWare 7.1.4 allows local users to gain root privileges by modifying the RELIANT_PATH environment variable to point to a malicious bin/hvenv program.

Directory traversal vulnerability in pkgadd in SCO UnixWare 7.1.4 before p534589 allows local users to create or append to arbitrary files via ".." sequences in an unspecified environment variable, probably PKGINST.

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 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 (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

Unspecified vulnerability in ptrace in SCO UnixWare 7.1.3 and 7.1.4 allows local users to gain privileges via unspecified vectors.

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.

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.

Stack-based buffer overflow in ppp in SCO Unixware 7.1.3 and 7.1.4, and possibly earlier versions, allows local users to execute arbitrary code via a long argument to the (1) prompt or (2) defprompt command.

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.

RPC portmapper (rpcbind) in SCO UnixWare 7.1.1 m5, 7.1.3 mp5, and 7.1.4 mp2 allows remote attackers or local users to cause a denial of service (lack of response) via multiple invalid portmap requests.

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.

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 on memory cache misses.

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.

main.c in cscope 15-4 and 15-5 creates temporary files with predictable filenames, which allows local users to overwrite arbitrary files via a symlink attack.

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.
