linux vulnerabilities
Details

Eric Windisch discovered flaw in how the Linux kernel's XFS file system replaces remote attributes. A local access with access to an XFS file system could exploit this flaw to escalate their privileges. (CVE-2015-0274)

A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2013-7421)

The Linux kernel's splice system call did not correctly validate its parameters. A local, unprivileged user could exploit this flaw to cause a denial of service (system crash). (CVE-2014-7822)

A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. (CVE-2014-9644)

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) failed to verify symlink size info. A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to cause a denial of service (system crash) or possibly cause other undesired behaviors. (CVE-2014-9728)

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not valid inode size information . A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to cause a denial of service (system crash) or possibly cause other undesired behaviors. (CVE-2014-9729)

Carl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) did not correctly verify the component length for symlinks. A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to cause a denial of service (system crash) or possibly cause other undesired behaviors. (CVE-2014-9730)

Carl H Lunde discovered an information leak in the UDF file system (CONFIG_UDF_FS). A local attacker, who is able to mount a malicous UDF file system image, could exploit this flaw to read potential sensitve kernel memory. (CVE-2014-9731)

  "details": "\nEric Windisch discovered flaw in how the Linux kernel\u0027s XFS file system\nreplaces remote attributes. A local access with access to an XFS file\nsystem could exploit this flaw to escalate their privileges.\n(CVE-2015-0274)\n\nA flaw was discovered in the automatic loading of modules in the crypto\nsubsystem of the Linux kernel. A local user could exploit this flaw to load\ninstalled kernel modules, increasing the attack surface and potentially\nusing this to gain administrative privileges. (CVE-2013-7421)\n\nThe Linux kernel\u0027s splice system call did not correctly validate its\nparameters. A local, unprivileged user could exploit this flaw to cause a\ndenial of service (system crash). (CVE-2014-7822)\n\nA flaw was discovered in the crypto subsystem when screening module names\nfor automatic module loading if the name contained a valid crypto module\nname, eg. vfat(aes). A local user could exploit this flaw to load installed\nkernel modules, increasing the attack surface and potentially using this to\ngain administrative privileges. (CVE-2014-9644)\n\nCarl H Lunde discovered that the UDF file system (CONFIG_UDF_FS) failed to\nverify symlink size info. A local attacker, who is able to mount a malicous\nUDF file system image, could exploit this flaw to cause a denial of service\n(system crash) or possibly cause other undesired behaviors.
