RHEL 5 / 6 : ecryptfs-utils (RHSA-2011:1241)

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1241 advisory. - ecryptfs: multiple flaws to mount/umount arbitrary locations and possibly disclose confidential information CVE-2011-1831,...

ecryptfs: multiple flaws to mount/umount arbitrary locations and possibly disclose confidential information

utils/mount.ecryptfsprivate.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to effectively replace any directory with a new filesystem, and consequently gain privileges, via a mount system call...

ecryptfs: multiple flaws to mount/umount arbitrary locations and possibly disclose confidential information

The lock-counter implementation in utils/mount.ecryptfsprivate.c in ecryptfs-utils before 90 allows local users to overwrite arbitrary files via unspecified vectors...

ecryptfs: multiple flaws to mount/umount arbitrary locations and possibly disclose confidential information

The encrypted private-directory setup process in utils/ecryptfs-setup-private in ecryptfs-utils before 90 does not properly ensure that the passphrase file is created, which might allow local users to bypass intended access restrictions at a certain time in the new-user creation steps...

ecryptfs-utils: incorrect mtab group ownership

When mount.ecrpytfsprivate before version 87-0ubuntu1.2 calls setreuid it doesn't also set the effective group id. So when it creates the new version, mtab.tmp, it's created with the group id of the user running mount.ecryptfsprivate...

ecryptfs: multiple flaws to mount/umount arbitrary locations and possibly disclose confidential information

utils/mount.ecryptfsprivate.c in ecryptfs-utils before 90 does not properly maintain the mtab file during error conditions, which allows local users to cause a denial of service table corruption or bypass intended unmounting restrictions via a umount system call...

Samba mtab lock file race condition

Multiple race conditions in the 1 mount.cifs and 2 umount.cifs programs in Samba 3.6 allow local users to cause a denial of service mounting outage via a SIGKILL signal during a time window when the /etc/mtab file exists...

samba/cifs-utils: mount.cifs and umount.cifs fail to anticipate RLIMIT_FSIZE

smbfs in Samba 3.5.8 and earlier attempts to use 1 mount.cifs to append to the /etc/mtab file and 2 umount.cifs to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process wi...

samba: mount.cifs improper device name and mountpoint strings sanitization

client/mount.cifs.c in mount.cifs in smbfs in Samba 3.4.5 and earlier does not verify that the 1 device name and 2 mountpoint strings are composed of valid characters, which allows local users to cause a denial of service mtab corruption via a crafted string...

samba/cifs-utils: mount.cifs and umount.cifs fail to anticipate RLIMIT_FSIZE

smbfs in Samba 3.5.8 and earlier attempts to use 1 mount.cifs to append to the /etc/mtab file and 2 umount.cifs to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process wi...

Samba mtab lock file race condition

Multiple race conditions in the 1 mount.cifs and 2 umount.cifs programs in Samba 3.6 allow local users to cause a denial of service mounting outage via a SIGKILL signal during a time window when the /etc/mtab file exists...

samba: Race condition by mount (mount.cifs) operations

client/mount.cifs.c in mount.cifs in smbfs in Samba 3.0.22, 3.0.28a, 3.2.3, 3.3.2, 3.4.0, and 3.4.5 allows local users to mount a CIFS share on an arbitrary mountpoint, and gain privileges, via a symlink attack on the mountpoint directory file...
