Debian DLA-1565-1 : glusterfs security update

Medium Nessus Plugin ID 118733

Synopsis

The remote Debian host is missing a security update.

Description

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.

For Debian 8 'Jessie', these problems have been fixed in version 3.5.2-2+deb8u5.

We recommend that you upgrade your glusterfs packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
