CVE-2011-2495 [LOW] kernel: /proc/PID/io infoleak
kernel: /proc/PID/io infoleak
fs/proc/base.c in the Linux kernel before 2.6.39.4 does not properly restrict access to /proc/#####/io files, which allows local users to obtain sensitive I/O statistics by polling a file, as demonstrated by discovering the length of another user's password.
Statement: This has been addressed in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-1212.html, https://rhn.redhat.com/errata/RHSA-2011-1189.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html. Red Hat Enterprise Linux 4 is now in Production 3 of the maintenance life-cycle, https://access.redhat.com/support/policy/updates/errata/, therefore the fix for this issue is not currently planned to be included in the future updates.

CVE-2011-2484 [MEDIUM] kernel: taskstats: duplicate entries in listener mode can lead to DoS
kernel: taskstats: duplicate entries in listener mode can lead to DoS
The add_del_listener function in kernel/taskstats.c in the Linux kernel 2.6.39.1 and earlier does not prevent multiple registrations of exit handlers, which allows local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.
Statement: This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 4 as it did not provide support for the Taskstats interface. This was fixed in Red Hat Enterprise Linux 5, 6, and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-1386.html, https://rhn.redhat.com/errata/RHSA-2011-1350.html and https://rhn.redhat.com/errata/RHSA-2011-1253.html.

CVE-2011-2695 [MEDIUM] kernel: ext4: kernel panic when writing data to the last block of sparse file
kernel: ext4: kernel panic when writing data to the last block of sparse file
Multiple off-by-one errors in the ext4 subsystem in the Linux kernel before 3.0-rc5 allow local users to cause a denial of service (BUG_ON and system crash) by accessing a sparse file in extent format with a write operation involving a block number corresponding to the largest possible 32-bit unsigned integer.

Multiple buffer overflows in net/wireless/nl80211.c in the Linux kernel before 2.6.39.2 allow local users to gain privileges by leveraging the CAP_NET_ADMIN capability during scan operations with a long SSID value.
Statement: This issue did not affect the versions of Linux kernel as shipped with Red Hat

Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call.

The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 does not validate a certain start parameter, which allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745.

kernel: DoS (crash) due slab corruption in inotify_init1 (incomplete fix for CVE-2010-4250)
Double free vulnerability in the inotify subsystem in the Linux kernel before 2.6.39 allows local users to cause a denial of service (system crash) via vectors involving failed attempts to create files. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-4250.

CVE-2011-1090 [MEDIUM] kernel: nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab
kernel: nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab
The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL.
Statement: This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not backport the upstream commit 4b580ee3 that introduced this issue.

CVE-2011-1021 [MEDIUM] kernel: /sys/kernel/debug/acpi/custom_method can bypass module restrictions
kernel: /sys/kernel/debug/acpi/custom_method can bypass module restrictions
drivers/acpi/debugfs.c in the Linux kernel before 3.0 allows local users to modify arbitrary kernel memory locations by leveraging root privileges to write to the /sys/kernel/debug/acpi/custom_method file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-4347.
Statement: The version of Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, and 6 as they did not include upstream commit a1a541d8 and a25ee920 that introduced the problem. This has been addressed in Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-1253.html.

CVE-2011-1020 [MEDIUM] kernel: no access restrictions of /proc/pid/* after setuid program exec
kernel: no access restrictions of /proc/pid/* after setuid program exec
The proc filesystem implementation in the Linux kernel 2.6.37 and earlier does not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allows local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls.
Statement: Red Hat Enterprise Linux 4 is now in Production 3 of the maintenance life-cycle, https://access.redhat.com/support/policy/updates/errata/, therefore the fix for this issue is not currently planned to be included in the future updates.

kernel: gro: reset dev and skb_iff on skb reuse
The napi_reuse_skb function in net/core/dev.c in the Generic Receive Offload (GRO) implementation in the Linux kernel before 2.6.38 does not reset the values of certain structure members, which might allow remote attackers to cause a denial of service (NULL pointer dereference) via a malformed VLAN frame.
Statement: This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 4 as it did not support Generic Receive Offload (GRO).

The cifs_find_smb_ses function in fs/cifs/connect.c in the Linux kernel before 2.6.36 does not properly determine the associations between users and sessions, which allows local users to bypass CIFS share authentication by leveraging a mount of a share by a different user.
Statement: This issue did not affect the versions of Linux kernel as shipped in Red Hat Enterprise Linux 4, 5, 6, and Red Hat Enterprise MRG as they did not ship mount.cifs with root setuid set.
