Moodle before 2.2.2 has a password and web services issue where when the user profile is updated the user password is reset if not specified.

Moodle before 2.2.2 has users' private files included in course backups

Moodle has a database activity export permission issue where the export function of the database activity module exports all entries even those from groups the user does not belong to

PyXML: hash table collisions CPU usage DoS (oCERT-2011-003)

PyXML: Hash table collisions CPU usage Denial of Service

mod_nss: FakeBasicAuth authentication bypass

Authentication bypass vulnerability in mod_nss 1.0.8 allows remote attackers to assume the identity of a valid user by using their certificate and entering 'password' as the password.

tog-pegasus: xml hash table collision CPU usage DoS

tog-Pegasus has a package hash collision DoS vulnerability

hardlink: Prone to symlink attacks

Hardlink before 0.1.2 operates on full file system objects path names which can allow a local attacker to use this flaw to conduct symlink attacks.

hardlink: Multiple integer overflows, when adding string lengths

Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, leading to hardlink executable crash or potentially arbitrary code execution with user privileges.

hardlink: Multiple stack-based buffer overflows when run on a tree with deeply nested directories

Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. A remote attacker could provide a specially-crafted directory tree, and trick the local user into consolidating it, leading to hardlink executable crash, or, potentially arbitrary code execution with the privileges of the user running the hardlink executable.

Samba mtab lock file race condition

Multiple race conditions in the (1) mount.cifs and (2) umount.cifs programs in Samba 3.6 allow local users to cause a denial of service (mounting outage) via a SIGKILL signal during a time window when the /etc/mtab~ file exists.

mount.ecrpytfs_private sets group owner of /etc/mtab to user's primary group

When mount.ecrpytfs_private before version 87-0ubuntu1.2 calls setreuid() it doesn't also set the effective group id. So when it creates the new version, mtab.tmp, it's created with the group id of the user running mount.ecryptfs_private.

gdk-pixbuf: GIF loader buffer overflow when initializing decompression tables

gdk-pixbuf through 2.31.1 has GIF loader buffer overflow when initializing decompression tables due to an input validation flaw

mod_perl: arbitrary Perl code execution in the context of the user account via a user-owned .htaccess

mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

An access bypass issue was found in Drupal 7.x before version 7.5. If a Drupal site has the ability to attach File upload fields to any entity type in the system or has the ability to point individual File upload fields to the private file directory in comments, and the parent node is denied access, non-privileged users can still download the file attached to the comment if they know or guess its direct URL.

dhcpv6: insufficient checking of DHCP options

The DHCPv6 client (dhcp6c) as used in the dhcpv6 project through 2011-07-25 allows remote DHCP servers to execute arbitrary commands via shell metacharacters in a hostname obtained from a DHCP message.

PackageKit: installs unsigned RPM packages as though they were signed

PackageKit 0.6.17 allows installation of unsigned RPM packages as though they were signed which may allow installation of non-trusted packages and execution of arbitrary code.

dirmngr: Improper dealing with blocking system calls, when verifying a certificate

dirmngr before 2.1.0 improperly handles certain system calls, which allows remote attackers to cause a denial of service (DOS) via a specially-crafted certificate.

unixODBC: possible buffer overrun in SQLDriverConnect()

The SQLDriverConnect() function in unixODBC before 2.2.14p2 have a possible buffer overflow condition when specifying a large value for SAVEFILE parameter in the connection string.

ConsoleKit: Policy restrictions break-out via remote Virtual Network Computing (VNC) session

In ConsoleKit before 0.4.2, an intended security policy restriction bypass was found. This flaw allows an authenticated system user to escalate their privileges by initiating a remote VNC session.

udisks: arbitrary Linux kernel loading flaw

udisks before 1.0.3 allows a local user to load arbitrary Linux kernel modules.
