There is a possible tty hijacking in shadow 4.x before 4.1.5 and sudo 1.x before 1.7.4 via "su - user -c program". The user session can be escaped to the parent session by using the TIOCSTI ioctl to push characters into the input buffer to be read by the next process.

The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack.

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.

functions/imap_general.php in SquirrelMail, as used in Red Hat Enterprise Linux (RHEL) 4 and 5, does not properly handle 8-bit characters in passwords, which allows remote attackers to cause a denial of service (disk consumption) by making many IMAP login attempts with different usernames, leading to the creation of many preference files. NOTE: this issue exists because of an incorrect fix for CVE-2010-2813.

The seunshare_mount function in sandbox/seunshare.c in seunshare in certain Red Hat packages of policycoreutils 2.0.83 and earlier in Red Hat Enterprise Linux (RHEL) 6 and earlier, and Fedora 14 and earlier, mounts a new directory on top of /tmp without assigning root ownership and the sticky bit to this new directory, which allows local users to replace or delete arbitrary /tmp files, and consequently cause a denial of service or possibly gain privileges, by running a setuid application that relies on /tmp, as demonstrated by the ksu application.

JBoss Seam 2 (jboss-seam2), as used in JBoss Enterprise Application Platform 4.3.0 for Red Hat Linux, does not properly sanitize inputs for JBoss Expression Language (EL) expressions, which allows remote attackers to execute arbitrary code via a crafted URL. NOTE: this is only a vulnerability when the Java Security Manager is not properly configured.

The cluster logical volume manager daemon (clvmd) in lvm2-cluster in LVM2 before 2.02.72, as used in Red Hat Global File System (GFS) and other products, does not verify client credentials upon a socket connection, which allows local users to cause a denial of service (daemon exit or logical-volume change) or possibly have unspecified other impact via crafted control commands.

A certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 4 on the ia64 platform allows local users to use ptrace on an arbitrary process, and consequently gain privileges, via vectors related to a missing ptrace_check_attach call.

Sun Sun Ray Server Software 3.x and 4.0 and Sun Ray Windows Connector 1.1 and 2.0 expose the LDAP password during a configuration step, which allows local users to discover the Sun Ray administration password, and obtain admin access to the Data Store and Administration GUI, via unspecified vectors related to the utconfig component of the Server Software and the uttscadm component of the Windows Connector.

Sun Sun Ray Server Software 3.1 through 4.0 does not properly restrict access, which allows remote attackers to discover the Sun Ray administration password, and obtain admin access to the Data Store and Administration GUI, via unspecified vectors.

Untrusted search path vulnerability in a certain Red Hat build script for Standards Based Linux Instrumentation for Manageability (sblim) libraries before 1-13a.el4_6.1 in Red Hat Enterprise Linux (RHEL) 4, and before 1-31.el5_2.1 in RHEL 5, allows local users to gain privileges via a malicious library in a certain subdirectory of /var/tmp, related to an incorrect RPATH setting, as demonstrated by a malicious libc.so library for tog-pegasus.

Unspecified vulnerability in HP Serviceguard for Linux; packaged for SuSE SLES8 and United Linux 1.0 before SG A.11.15.07, SuSE SLES9 and SLES10 before SG A.11.16.10, and Red Hat Enterprise Linux (RHEL) before SG A.11.16.10; allows remote attackers to obtain unauthorized access via unspecified vectors.

The clip_mkip function in net/atm/clip.c of the ATM subsystem in Linux kernel allows remote attackers to cause a denial of service (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (freed pointer dereference).
