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.

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

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.

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

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.

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.

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.

Integer overflow in the TIFFFetchStripThing function in tifdirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

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.

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.

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.

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.
