Debian LTS Advisory ([SECURITY] [DLA 1565-1] glusterfs security update)

Published: 2018-11-05 23:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:S/C:P/I:P/A:P

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
glusterfs on Debian Linux

Recommendations:
For Debian 8 'Jessie', these problems have been fixed in version 3.5.2-2+deb8u5. We recommend that you upgrade your glusterfs Linux Distribution Packages.

Summary:
Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows and path traversal issues may lead to information disclosure, denial-of-service or the execution of arbitrary code. CVE-2018-14651 It was found that the fix for CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, and CVE-2018-10926 was incomplete. A remote, authenticated attacker could use one of these flaws to execute arbitrary code, create arbitrary files, or cause denial of service on glusterfs server nodes via symlinks to relative paths. CVE-2018-14652 The Gluster file system is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service. CVE-2018-14653 The Gluster file system is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact. CVE-2018-14659 The Gluster file system is vulnerable to a denial of service attack via use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory. CVE-2018-14661 It was found that usage of snprintf function in feature/locks translator of glusterfs server was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
