Redhat » Linux » 7.0 alpha : Security Vulnerabilities, CVEs, CVSS score >= 5

Format string vulnerability in use_syslog() function in LPRng 3.6.24 allows remote attackers to execute arbitrary commands.

Buffer overflow in ncurses library allows local users to execute arbitrary commands via long environmental information such as TERM or TERMINFO_DIRS.

modprobe in the modutils 2.3.x package on Linux systems allows a local user to execute arbitrary commands via shell metacharacters.

Buffer overflow in pam_localuser PAM module in Red Hat Linux 7.x and 6.x allows attackers to gain privileges.

Format string vulnerability in startprinting() function of printjob.c in BSD-based lpr lpd package may allow local users to gain privileges via an improper syslog call that uses format strings from the checkremote() call.

ping in iputils before 20001010, as distributed on Red Hat Linux 6.2 through 7J and other operating systems, does not drop privileges after acquiring a raw socket, which increases ping's exposure to bugs that otherwise would occur at lower privileges.

Zope before 2.2.4 does not properly compute local roles, which could allow users to bypass specified access restrictions and gain privileges.

Format string vulnerability in print_client in icecast 1.3.8beta2 and earlier allows remote attackers to execute arbitrary commands.

Buffer overflow in micq client 0.4.6 and earlier allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long Description field.

licq before 1.0.3 allows remote attackers to execute arbitrary commands via shell metacharacters in a URL.

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.

Format string vulnerability in Mutt before 1.2.5 allows a remote malicious IMAP server to execute arbitrary commands.

Format string vulnerability in the default logging callback function _sasl_syslog in common.c in Cyrus SASL library (cyrus-sasl) may allow remote attackers to execute arbitrary commands.

OpenSSH 3.0.1 and earlier with UseLogin enabled does not properly cleanse critical environment variables such as LD_PRELOAD, which allows local users to gain root privileges.

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.

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.

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.

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.

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.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.

Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."

Squid 2.4 STABLE3 and earlier does not properly disable HTCP, even when "htcp_port 0" is specified in squid.conf, which could allow remote attackers to bypass intended access restrictions.

Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.
