glusterfs: Arbitrary file creation on storage server allows for execution of arbitrary code

A flaw was found in RPC request using gfs2_create_req in glusterfs server. An authenticated attacker could use this flaw to create arbitrary files and execute arbitrary code on glusterfs server nodes.

glusterfs: File status information leak and denial of service

A flaw was found in RPC request using gfs3_lookup_req in glusterfs server. An authenticated attacker could use this flaw to leak information and execute remote denial of service by crashing gluster brick process.

glusterfs: Device files can be created in arbitrary locations

A flaw was found in RPC request using gfs3_mknod_req supported by glusterfs server. An authenticated attacker could use this flaw to write files to an arbitrary location via path traversal and execute arbitrary code on a glusterfs server node.

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.

ttembed: use of untrusted length field may lead to denial of service

An input validation flaw exists in ttembed. With a crafted input file, an attacker may be able to trigger a denial of service condition due to ttembed trusting attacker controlled values.

ttembed: failure to check file bounds may lead to input file corruption

Certain input files may trigger an integer overflow in ttembed input file processing. This overflow could potentially lead to corruption of the input file due to a lack of checking return codes of fgetc/fputc function calls.

Improper input validation bug in DNS resolver component of Knot Resolver before 2.4.1 allows remote attacker to poison cache.

samba: Confidential attribute disclosure via substring search

The Samba Active Directory LDAP server was vulnerable to an information disclosure flaw because of missing access control checks. An authenticated attacker could use this flaw to extract confidential attribute values using LDAP search expressions. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.

lftp: particular remote file names may lead to current working directory erased

It has been discovered that lftp up to and including version 4.8.3 does not properly sanitize remote file names, leading to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim's system.

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.

glusterfs: Information Exposure in posix_get_file_contents function in posix-helpers.c

An information disclosure vulnerability was discovered in glusterfs server. An attacker could issue a xattr request via glusterfs FUSE to determine the existence of any file.

glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory

A flaw was found in the way dic_unserialize function of glusterfs does not handle negative key length values. An attacker could use this flaw to read memory from other locations into the stored dict value.

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.

python-cryptography: GCM tag forgery via truncated tag in finalize_with_tag API

A flaw was found in python-cryptography versions between >=1.9.0 and <2.3. The finalize_with_tag API did not enforce a minimum tag length. If a user did not validate the input length prior to passing it to finalize_with_tag an attacker could craft an invalid payload with a shortened tag (e.g. 1 byte) such that they would have a 1 in 256 chance of passing the MAC check. GCM tag forgeries can cause key leakage.

jolokia: system-wide CSRF that could lead to Remote Code Execution

A flaw was found in Jolokia versions from 1.2 to before 1.6.1. Affected versions are vulnerable to a system-wide CSRF. This holds true for properly configured instances with strict checking for origin and referrer headers. This could result in a Remote Code Execution attack.

A flaw was found in moodle before versions 3.5.1, 3.4.4, 3.3.7, 3.1.13. When a quiz question bank is imported, it was possible for the question preview that is displayed to execute JavaScript that is written into the question bank.

A flaw was found in moodle before versions 3.5.1, 3.4.4, 3.3.7, 3.1.13. It was possible for the core_course_get_categories web service to return hidden categories, which should be omitted when fetching course categories.

A flaw was found in libgit2 before version 0.27.3. A missing check in git_delta_apply function in delta.c file, may lead to an out-of-bound read while reading a binary delta file. An attacker may use this flaw to cause a Denial of Service.

atomic-openshift: Malicious network-policy can cause Openshift Routing DoS when using ovs-networkpolicy plugin

In atomic-openshift before version 3.10.9 a malicious network-policy configuration can cause Openshift Routing to crash when using ovs-networkpolicy plugin. An attacker can use this flaw to cause a Denial of Service (DoS) attack on an Openshift 3.9, or 3.7 Cluster.

ansible: Inventory variables are loaded from current working directory when running ad-hoc command that can lead to code execution

In ansible it was found that inventory variables are loaded from current working directory when running ad-hoc command which are under attacker's control, allowing to run arbitrary code as a result.
