Dmidecode before 3.5 allows -dump-bin to overwrite a local file. This has security relevance because, for example, execution of Dmidecode via Sudo is plausible.

zutils version prior to version 1.8-pre2 contains a Buffer Overflow vulnerability in zcat that can result in Potential denial of service or arbitrary code execution. This attack appear to be exploitable via the victim openning a crafted compressed file. This vulnerability appears to have been fixed in 1.8-pre2.

GKSu 2.0.2, when sudo-mode is not enabled, uses " (double quote) characters in a gksu-run-helper argument, which allows attackers to execute arbitrary commands in certain situations involving an untrusted substring within this argument, as demonstrated by an untrusted filename encountered during installation of a VirtualBox extension pack.

usersfile.c in liboath in OATH Toolkit before 2.4.1 does not properly handle lines containing an invalid one-time-password (OTP) type and a user name in /etc/users.oath, which causes the wrong line to be updated when invalidating an OTP and allows context-dependent attackers to conduct replay attacks, as demonstrated by a commented out line when using libpam-oath.

An array index error, leading to heap-based buffer overflow was found in the way CVS version control system applied certain delta fragments changes from input file in the RCS (Revision Control System file) format. A local attacker, with access to the system controlling the repository, could store a specially-crafted RCS file into the CVS repository and trick the remote user to checkout (update their CVS repository tree) with this file, which could lead to arbitrary code execution with the privileges of the CVS server process on the system hosting the CVS repository.

Multiple cross-site scripting (XSS) vulnerabilities in Samizdat before 0.6.2 allow remote authenticated users to inject arbitrary web script or HTML via the (1) message title or (2) user full name.

Mail Notification 4.0, when WITHSSL is set to 0 at compile time, uses unencrypted connections for accounts configured with SSL/TLS, which allows remote attackers to obtain sensitive information by sniffing the network.
