Vulnerabilities (CVE)

A certain Red Hat build script for nfs-utils before 1.0.9-35z.el5_2 on Red Hat Enterprise Linux (RHEL) 5 omits TCP wrappers support, which might allow remote attackers to bypass intended access restrictions.

nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.

usr/mgmt_ipc.c in iscsid in open-iscsi (iscsi-initiator-utils) before 2.0-865 checks the client's UID on the listening AF_LOCAL socket instead of the new connection, which allows remote attackers to access the management interface and cause a denial of service (iscsid exit or iSCSI connection loss).

Cross-site scripting (XSS) vulnerability in setroubleshoot 2.0.5 allows local users to inject arbitrary web script or HTML via a crafted (1) file or (2) process name, which triggers an Access Vector Cache (AVC) log entry in a log file used during composition of HTML documents for sealert.

The sysfs_readdir function in the Linux kernel 2.6, as used in Red Hat Enterprise Linux (RHEL) 4.5 and other distributions, allows users to cause a denial of service (kernel OOPS) by dereferencing a null pointer to an inode in a dentry.

Certain Red Hat Enterprise Linux (RHEL) 4 and 5 packages for OpenSSH, as signed in August 2008 using a legitimate Red Hat GPG key, contain an externally introduced modification (Trojan Horse) that allows the package authors to have an unknown impact. NOTE: since the malicious packages were not distributed from any official Red Hat sources, the scope of this issue is restricted to users who may have obtained these packages through unofficial distribution points. As of 20080827, no unofficial di ...

NOTE: some of these details are obtained from third party information.

XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.

usr/log.c in iscsid in open-iscsi (iscsi-initiator-utils) before 2.0-865 uses a semaphore with insecure permissions (world-writable/world-readable) for managing log messages using shared memory, which allows local users to cause a denial of service (hang) by grabbing the semaphore.

Cross-site scripting (XSS) vulnerability in the mod_negotiation module in the Apache HTTP Server 2.2.6 and earlier in the 2.2.x series, 2.0.61 and earlier in the 2.0.x series, and 1.3.39 and earlier in the 1.3.x series allows remote authenticated users to inject arbitrary web script or HTML by uploading a file with a name containing XSS sequences and a file extension, which leads to injection within a (1) "406 Not Acceptable" or (2) "300 Multiple Choices" HTTP response when the extension is omit ...

The file watch implementation in the audit subsystem (auditctl -w) in the Red Hat Enterprise Linux (RHEL) 4 kernel 2.6.9 allows local users to cause a denial of service (kernel panic) by replacing a watched file, which does not cause the watch on the old inode to be dropped.

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).

The kernel in Red Hat Enterprise Linux 3, when running on SMP systems, allows local users to cause a denial of service (deadlock) by running the shmat function on an shm at the same time that shmctl is removing that shm (IPC_RMID), which prevents a spinlock from being unlocked.

Directory traversal vulnerability in the contains_dot_dot function in src/names.c in GNU tar allows user-assisted remote attackers to overwrite arbitrary files via certain //.. (slash slash dot dot) sequences in directory symlinks in a TAR archive.

Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU GDB testsuite, a different vulnerability than CVE-2008-2365.
