CVE-2011-1751 2 Qemu, Redhat 2 Qemu, Enterprise Linux 2025-04-11 N/A
The pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers."
CVE-2011-1763 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
The get_free_port function in Xen allows local authenticated DomU users to cause a denial of service or possibly gain privileges via unspecified vectors involving a new event channel port.

net/ipv4/ip_gre.c in the Linux kernel before 2.6.34, when ip_gre is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading.
CVE-2011-1768 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Enterprise Mrg 2025-04-11 N/A
The tunnels implementation in the Linux kernel before 2.6.34, when tunnel functionality is configured as a module, allows remote attackers to cause a denial of service (OOPS) by sending a packet during module loading.
CVE-2011-1769 2 Redhat, Systemtap 2 Enterprise Linux, Systemtap 2025-04-11 N/A
SystemTap 1.4 and earlier, when unprivileged (aka stapusr) mode is enabled, allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted ELF program with DWARF expressions that are not properly handled by a stap script that performs context variable access.
CVE-2011-1775 2 Redhat, Tigervnc 2 Enterprise Linux, Tigervnc 2025-04-11 N/A
The CSecurityTLS::processMsg function in common/rfb/CSecurityTLS.cxx in the vncviewer component in TigerVNC 1.1beta1 does not properly verify the server's X.509 certificate, which allows man-in-the-middle attackers to spoof a TLS VNC server via an arbitrary certificate.
CVE-2011-1776 2 Linux, Redhat 8 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 5 more 2025-04-11 6.1 Medium
The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before 2.6.39 does not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allows physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577.
CVE-2011-1780 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
The instruction emulation in Xen 3.0.3 allows local SMP guest users to cause a denial of service (host crash) by replacing the instruction that causes the VM to exit in one thread with a different instruction in a different thread.
CVE-2011-1910 2 Isc, Redhat 2 Bind, Enterprise Linux 2025-04-11 N/A
Off-by-one error in named in ISC BIND 9.x before 9.7.3-P1, 9.8.x before 9.8.0-P2, 9.4-ESV before 9.4-ESV-R4-P1, and 9.6-ESV before 9.6-ESV-R4-P1 allows remote DNS servers to cause a denial of service (assertion failure and daemon exit) via a negative response containing large RRSIG RRsets.
CVE-2011-1831 2 Ecryptfs, Redhat 3 Ecryptfs-utils, Ecryptfs Utils, Enterprise Linux 2025-04-11 N/A
utils/mount.ecryptfs_private.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.
CVE-2011-1921 2 Apache, Redhat 2 Subversion, Enterprise Linux 2025-04-11 N/A
The mod_dav_svn module for the Apache HTTP Server, as distributed in Apache Subversion 1.5.x and 1.6.x before 1.6.17, when the SVNPathAuthz short_circuit option is disabled, does not properly enforce permissions for files that had been publicly readable in the past, which allows remote attackers to obtain sensitive information via a replay REPORT operation.
CVE-2011-1832 2 Ecryptfs, Redhat 3 Ecryptfs-utils, Ecryptfs Utils, Enterprise Linux 2025-04-11 N/A
utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 does not properly check mountpoint permissions, which allows local users to remove directories via a umount system call.
CVE-2011-1834 2 Ecryptfs, Redhat 3 Ecryptfs-utils, Ecryptfs Utils, Enterprise Linux 2025-04-11 N/A
utils/mount.ecryptfs_private.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.
CVE-2011-1835 2 Ecryptfs, Redhat 3 Ecryptfs-utils, Ecryptfs Utils, Enterprise Linux 2025-04-11 N/A
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.
CVE-2011-1837 2 Ecryptfs, Redhat 3 Ecryptfs-utils, Ecryptfs Utils, Enterprise Linux 2025-04-11 N/A
The lock-counter implementation in utils/mount.ecryptfs_private.c in ecryptfs-utils before 90 allows local users to overwrite arbitrary files via unspecified vectors.
CVE-2009-3556 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-04-11 N/A
A certain Red Hat configuration step for the qla2xxx driver in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5, when N_Port ID Virtualization (NPIV) hardware is used, sets world-writable permissions for the (1) vport_create and (2) vport_delete files under /sys/class/scsi_host/, which allows local users to make arbitrary changes to SCSI host attributes by modifying these files.
CVE-2011-1926 2 Cmu, Redhat 2 Cyrus Imap Server, Enterprise Linux 2025-04-11 N/A
The STARTTLS implementation in Cyrus IMAP Server before 2.4.7 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.
CVE-2011-1929 2 Dovecot, Redhat 2 Dovecot, Enterprise Linux 2025-04-11 N/A
lib-mail/message-header-parser.c in Dovecot 1.2.x before 1.2.17 and 2.0.x before 2.0.13 does not properly handle '\0' characters in header names, which allows remote attackers to cause a denial of service (daemon crash or mailbox corruption) via a crafted e-mail message.
CVE-2011-1936 2 Redhat, Xen 2 Enterprise Linux, Xen 2025-04-11 N/A
Xen, when using x86 Intel processors and the VMX virtualization extension is enabled, does not properly handle cpuid instruction emulation when exiting the VM, which allows local guest users to cause a denial of service (guest crash) via unspecified vectors.
CVE-2011-1944 2 Redhat, Xmlsoft 3 Enterprise Linux, Libxml, Libxml2 2025-04-11 N/A
Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.
