Multiple integer overflows in (1) OPVPOutputDev.cxx and (2) oprs/OPVPSplash.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allow remote attackers to execute arbitrary code via a crafted PDF file, which triggers a heap-based buffer overflow.
The OPVPWrapper::loadDriver function in oprs/OPVPWrapper.cxx in the pdftoopvp filter in CUPS and cups-filters before 1.0.47 allows local users to gain privileges via a Trojan horse driver in the same directory as the PDF file.
The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.
The configuration file for the FastCGI PHP support for lighttpd before 1.4.28 on Debian GNU/Linux creates a socket file with a predictable name in /tmp, which allows local users to hijack the PHP control socket and perform unauthorized actions such as forcing the use of a different version of PHP via a symlink attack or a race condition.
rssh 2.3.2, as used by Debian, Fedora, and others, when the rsync protocol is enabled, allows local users to bypass intended restricted shell access via a (1) "-e" or (2) "--" command line option.
CUPS 1.4.4, when running in certain Linux distributions such as Debian GNU/Linux, stores the web interface administrator key in /var/run/cups/certs/0 using certain permissions, which allows local users in the lpadmin group to read or write arbitrary files as root by leveraging the web interface.
The Debian php_crypt_revamped.patch patch for PHP 5.3.x, as used in the php5 package before 5.3.3-7+squeeze4 in Debian GNU/Linux squeeze, the php5 package before 5.3.2-1ubuntu4.17 in Ubuntu 10.04 LTS, and the php5 package before 5.3.5-1ubuntu7.10 in Ubuntu 11.04, does not properly handle an empty salt string, which might allow remote attackers to bypass authentication by leveraging an application that relies on the PHP crypt function to choose a salt for password hashing.
The default configuration of the shell_escape_commands directive in conf/texmf.d/95NonPath.cnf in the tex-common package before 2.08.1 in Debian GNU/Linux squeeze, Ubuntu 10.10 and 10.04 LTS, and possibly other operating systems lists certain programs, which might allow remote attackers to execute arbitrary code via a crafted TeX document.
drivers/connector/connector.c in the Linux kernel before 2.6.32.8 allows local users to cause a denial of service (memory consumption and system crash) by sending the kernel many NETLINK_CONNECTOR messages.
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.
