CVE-2018-10923

glusterfs: I/O to arbitrary devices on storage server

It was found that the "mknod" call derived from mknod(2) can create files pointing to devices on a glusterfs server node. An authenticated attacker could use this to create an arbitrary device and read data from any device attached to the glusterfs server node.

postgresql: Certain host connection parameters defeat client-side security defenses

A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq was used with "host" or "hostaddr" connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction. Postgresql versions before 10.5, 9.6.10, 9.5.14, 9.4.19, and 9.3.24 are affected.

vdsm: calls to qemu-img are not protected by prlimit/ulimit

It was found that vdsm before version 4.20.37 invokes qemu-img on untrusted inputs without limiting resources. By uploading a specially crafted image, an attacker could cause the qemu-img process to consume unbounded amounts of memory of CPU time, causing a denial of service condition that could potentially impact other users of the host.

glusterfs: Stack-based buffer overflow in server-rpc-fops.c allows remote attackers to execute arbitrary code

It was found that glusterfs server is vulnerable to multiple stack based buffer overflows due to functions in server-rpc-fopc.c allocating fixed size buffers using 'alloca(3)'. An authenticated attacker could exploit this by mounting a gluster volume and sending a string longer that the fixed buffer size to cause crash or potential code execution.

glusterfs: Unsanitized file names in debug/io-stats translator can allow remote attackers to execute arbitrary code

It was found that glusterfs server does not properly sanitize file paths in the "trusted.io-stats-dump" extended attribute which is used by the "debug/io-stats" translator. Attacker can use this flaw to create files and execute arbitrary code. To exploit this attacker would require sufficient access to modify the extended attributes of files on a gluster volume.

CVE-2018-10897

yum-utils: reposync: improper path validation may lead to directory traversal

A directory traversal issue was found in reposync, a part of yum-utils, where reposync fails to sanitize paths in remote repository configuration files. If an attacker controls a repository, they may be able to copy files outside of the destination directory on the targeted system via path traversal. If reposync is running with heightened privileges on a targeted system, this flaw could potentially result in system compromise via the overwriting of critical system files. Version 1.1.31 and older are believed to be affected.

Ansible 2.5 prior to 2.5.5, and 2.4 prior to 2.4.5, do not honor the no_log task flag for failed tasks. When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.

guava: Unbounded memory allocation in AtomicDoubleArray and CompoundOrdering classes allow remote attackers to cause a denial of service

Unbounded memory allocation in Google Guava 11.0 through 24.x before 24.1.1 allows remote attackers to conduct denial of service attacks against servers that depend on this library and deserialize attacker-provided data, because the AtomicDoubleArray class (when serialized with Java serialization) and the CompoundOrdering class (when serialized with GWT serialization) perform eager allocation without appropriate checks on what a client has sent and whether the data size is reasonable.
