CVE-2011-4339 2 Ipmitool Project, Redhat 2 Ipmitool, Enterprise Linux 2026-06-16 3.6 LOW N/A
ipmievd (aka the IPMI event daemon) in OpenIPMI, as used in the ipmitool package 1.8.11 in Red Hat Enterprise Linux (RHEL) 6, Debian GNU/Linux, Fedora 16, and other products uses 0666 permissions for its ipmievd.pid PID file, which allows local users to kill arbitrary processes by writing to this file.
CVE-2011-4111 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Enterprise Linux Server Supplementary 2026-06-16 6.8 MEDIUM N/A
Buffer overflow in the ccid_card_vscard_handle_message function in hw/ccid-card-passthru.c in QEMU before 0.15.2 and 1.x before 1.0-rc4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted VSC_ATR message.
CVE-2011-4097 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 4.9 MEDIUM 5.5 MEDIUM
Integer overflow in the oom_badness function in mm/oom_kill.c in the Linux kernel before 3.1.8 on 64-bit platforms allows local users to cause a denial of service (memory consumption or process termination) by using a certain large amount of memory.
CVE-2011-3637 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 4.9 MEDIUM 5.5 MEDIUM
The m_stop function in fs/proc/task_mmu.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (OOPS) via vectors that trigger an m_start error.
CVE-2011-3632 3 Debian, Hardlink Project, Redhat 3 Debian Linux, Hardlink, Enterprise Linux 2026-06-16 3.6 LOW 7.1 HIGH
Hardlink before 0.1.2 operates on full file system objects path names which can allow a local attacker to use this flaw to conduct symlink attacks.
CVE-2011-3631 3 Debian, Hardlink Project, Redhat 3 Debian Linux, Hardlink, Enterprise Linux 2026-06-16 6.8 MEDIUM 8.8 HIGH
Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, leading to hardlink executable crash or potentially arbitrary code execution with user privileges.
CVE-2011-3630 3 Debian, Hardlink Project, Redhat 3 Debian Linux, Hardlink, Enterprise Linux 2026-06-16 6.8 MEDIUM 8.8 HIGH
Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. A remote attacker could provide a specially-crafted directory tree, and trick the local user into consolidating it, leading to hardlink executable crash, or, potentially arbitrary code execution with the privileges of the user running the hardlink executable.
CVE-2011-3593 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 5.7 MEDIUM N/A
A certain Red Hat patch to the vlan_hwaccel_do_receive function in net/8021q/vlan_core.c in the Linux kernel 2.6.32 on Red Hat Enterprise Linux (RHEL) 6 allows remote attackers to cause a denial of service (system crash) via priority-tagged VLAN frames.
CVE-2011-3585 2 Redhat, Samba 2 Enterprise Linux, Samba 2026-06-16 1.9 LOW 4.7 MEDIUM
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.
CVE-2011-3363 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 6.1 MEDIUM 6.5 MEDIUM
The setup_cifs_sb function in fs/cifs/connect.c in the Linux kernel before 2.6.39 does not properly handle DFS referrals, which allows remote CIFS servers to cause a denial of service (system crash) by placing a referral at the root of a share.
CVE-2011-3348 2 Apache, Redhat 3 Http Server, Enterprise Linux, Jboss Enterprise Web Server 2026-06-16 4.3 MEDIUM N/A
The mod_proxy_ajp module in the Apache HTTP Server before 2.2.21, when used with mod_proxy_balancer in certain configurations, allows remote attackers to cause a denial of service (temporary "error state" in the backend server) via a malformed HTTP request.
CVE-2011-3347 1 Redhat 1 Enterprise Linux 2026-06-16 4.6 MEDIUM N/A
A certain Red Hat patch to the be2net implementation in the kernel package before 2.6.32-218.el6 on Red Hat Enterprise Linux (RHEL) 6, when promiscuous mode is enabled, allows remote attackers to cause a denial of service (system crash) via non-member VLAN packets.
CVE-2011-3346 3 Qemu, Redhat, Xen 3 Qemu, Enterprise Linux, Xen 2026-06-16 4.0 MEDIUM N/A
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.
CVE-2011-3191 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 8.3 HIGH 8.8 HIGH
Integer signedness error in the CIFSFindNext function in fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large length value in a response to a read request for a directory.
CVE-2011-3188 3 F5, Linux, Redhat 15 Arx, Big-ip Access Policy Manager, Big-ip Analytics and 12 more 2026-06-16 6.4 MEDIUM 9.1 CRITICAL
The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets.
CVE-2011-3045 6 Debian, Fedoraproject, Google and 3 more 13 Debian Linux, Fedora, Chrome and 10 more 2026-06-16 6.8 MEDIUM 8.8 HIGH
Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.
CVE-2011-2942 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-06-16 6.8 MEDIUM N/A
A certain Red Hat patch to the __br_deliver function in net/bridge/br_forward.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging connectivity to a network interface that uses an Ethernet bridge device.
CVE-2011-2897 3 Debian, Gnome, Redhat 3 Debian Linux, Gdk-pixbuf, Enterprise Linux 2026-06-16 7.5 HIGH 9.8 CRITICAL
gdk-pixbuf through 2.31.1 has GIF loader buffer overflow when initializing decompression tables due to an input validation flaw
CVE-2011-2767 4 Apache, Canonical, Debian and 1 more 7 Mod Perl, Ubuntu Linux, Debian Linux and 4 more 2026-06-16 10.0 HIGH 9.8 CRITICAL
mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.
CVE-2011-2726 4 Debian, Drupal, Fedoraproject and 1 more 4 Debian Linux, Drupal, Fedora and 1 more 2026-06-16 5.0 MEDIUM 7.5 HIGH
An access bypass issue was found in Drupal 7.x before version 7.5. If a Drupal site has the ability to attach File upload fields to any entity type in the system or has the ability to point individual File upload fields to the private file directory in comments, and the parent node is denied access, non-privileged users can still download the file attached to the comment if they know or guess its direct URL.
