Format string vulnerability in exim (3.22-10 in Red Hat, 3.12 in Debian and 3.16 in Conectiva) in batched SMTP mode allows a remote attacker to execute arbitrary code via format strings in SMTP mail headers.
Apache on Red Hat Linux with with the UserDir directive enabled generates different error codes when a username exists and there is no public_html directory and when the username does not exist, which could allow remote attackers to determine valid usernames on the server.
The default configuration of the DVI print filter (dvips) in Red Hat Linux 7.0 and earlier does not run dvips in secure mode when dvips is executed by lpd, which could allow remote attackers to gain privileges by printing a DVI file that contains malicious commands.
Red Hat Linux 7.1 sets insecure permissions on swap files created during installation, which can allow a local attacker to gain additional privileges by reading sensitive information from the swap file, such as passwords.
expect before 5.32 searches for its libraries in /var/tmp before other directories, which could allow local users to gain root privileges via a Trojan horse library that is accessed by mkpasswd.
tcl/tk package (tcltk) 8.3.1 searches for its libraries in the current working directory before other directories, which could allow local users to execute arbitrary code via a Trojan horse library that is under a user-controlled directory.
Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.
slapd in OpenLDAP 1.x before 1.2.12, and 2.x before 2.0.8, allows remote attackers to cause a denial of service (crash) via an invalid Basic Encoding Rules (BER) length field.
Buffer overflow in (1) wrapping and (2) unwrapping functions of slrn news reader before 0.9.7.0 allows remote attackers to execute arbitrary commands via a long message header.
