KDE Display Manager (KDM) in KDE 3.2.0 up to 3.5.3 allows local users to read arbitrary files via a symlink attack related to the session type for login.

Heap-based buffer overflow in the encodeURI and decodeURI functions in the kjs JavaScript interpreter engine in KDE 3.2.0 through 3.5.0 allows remote attackers to execute arbitrary code via a crafted, UTF-8 encoded URI.

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."

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.

kcheckpass in KDE 3.2.0 up to 3.4.2 allows local users to gain root access via a symlink attack on lock files.

langen2kvtml in KDE 3.0 to 3.4.2 creates insecure temporary files in /tmp with predictable names, which allows local users to overwrite arbitrary files.

Multiple integer overflows in libgadu, as used in Kopete in KDE 3.2.3 to 3.4.1, ekg before 1.6rc3, GNU Gadu, CenterICQ, Kadu, and other packages, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an incoming message.

The (1) Kate and (2) Kwrite applications in KDE KDE 3.2.x through 3.4.0 do not properly set the same permissions on the backup file as were set on the original file, which could allow local users and possibly remote attackers to obtain sensitive information.

Multiple vulnerabilities in fliccd, when installed setuid root as part of the kdeedu Kstars support for Instrument Neutral Distributed Interface (INDI) in KDE 3.3 to 3.3.2, allow local users and remote attackers to execute arbitrary code via stack-based buffer overflows.
