CVE-2021-32749 2 Fail2ban, Fedoraproject 2 Fail2ban, Fedora 2021-11-28 6.8 MEDIUM 8.1 HIGH
fail2ban is a daemon to ban hosts that cause multiple authentication errors. In versions 0.9.7 and prior, 0.10.0 through 0.10.6, and 0.11.0 through 0.11.2, there is a vulnerability that leads to possible remote code execution in the mailing action mail-whois. Command `mail` from mailutils package used in mail actions like `mail-whois` can execute command if unescaped sequences (`\n~`) are available in "foreign" input (for instance in whois output). To exploit the vulnerability, an attacker would need to insert malicious characters into the response sent by the whois server, either via a MITM attack or by taking over a whois server. The issue is patched in versions 0.10.7 and 0.11.3. As a workaround, one may avoid the usage of action `mail-whois` or patch the vulnerability manually.
CVE-2021-31556 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2021-11-28 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the Oauth extension for MediaWiki through 1.35.2. MWOAuthConsumerSubmitControl.php does not ensure that the length of an RSA key will fit in a MySQL blob.
CVE-2021-42762 4 Debian, Fedoraproject, Webkitgtk and 1 more 4 Debian Linux, Fedora, Webkitgtk and 1 more 2021-11-26 4.6 MEDIUM 5.3 MEDIUM
BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit before 2.34.1 allows a limited sandbox bypass that allows a sandboxed process to trick host processes into thinking the sandboxed process is not confined by the sandbox, by abusing VFS syscalls that manipulate its filesystem namespace. The impact is limited to host services that create UNIX sockets that WebKit mounts inside its sandbox, and the sandboxed process remains otherwise confined. NOTE: this is similar to CVE-2021-41133.
CVE-2021-41798 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2021-11-26 4.3 MEDIUM 6.1 MEDIUM
MediaWiki before 1.36.2 allows XSS. Month related MediaWiki messages are not escaped before being used on the Special:Search results page.
CVE-2021-41799 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2021-11-26 5.0 MEDIUM 7.5 HIGH
MediaWiki before 1.36.2 allows a denial of service (resource consumption because of lengthy query processing time). ApiQueryBacklinks (action=query&list=backlinks) can cause a full table scan.
CVE-2021-27836 2 Fedoraproject, Libxls Project 2 Fedora, Libxls 2021-11-26 4.3 MEDIUM 6.5 MEDIUM
An issue was discoverered in in function xls_getWorkSheet in xls.c in libxls 1.6.2, allows attackers to cause a denial of service, via a crafted XLS file.
CVE-2021-21394 2 Fedoraproject, Matrix 2 Fedora, Synapse 2021-11-23 4.0 MEDIUM 6.5 MEDIUM
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.28.0 Synapse is missing input validation of some parameters on the endpoints used to confirm third-party identifiers could cause excessive use of disk space and memory leading to resource exhaustion. Note that the groups feature is not part of the Matrix specification and the chosen maximum lengths are arbitrary. Not all clients might abide by them. Refer to referenced GitHub security advisory for additional details including workarounds.
CVE-2021-21393 2 Fedoraproject, Matrix 2 Fedora, Synapse 2021-11-23 4.3 MEDIUM 6.5 MEDIUM
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.28.0 Synapse is missing input validation of some parameters on the endpoints used to confirm third-party identifiers could cause excessive use of disk space and memory leading to resource exhaustion. Note that the groups feature is not part of the Matrix specification and the chosen maximum lengths are arbitrary. Not all clients might abide by them. Refer to referenced GitHub security advisory for additional details including workarounds.
CVE-2021-25281 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 7.5 HIGH 9.8 CRITICAL
An issue was discovered in through SaltStack Salt before 3002.5. salt-api does not honor eauth credentials for the wheel_async client. Thus, an attacker can remotely run any wheel modules on the master.
CVE-2021-21392 2 Fedoraproject, Matrix 2 Fedora, Synapse 2021-11-23 4.9 MEDIUM 6.3 MEDIUM
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.28.0 requests to user provided domains were not restricted to external IP addresses when transitional IPv6 addresses were used. Outbound requests to federation, identity servers, when calculating the key validity for third-party invite events, sending push notifications, and generating URL previews are affected. This could cause Synapse to make requests to internal infrastructure on dual-stack networks. See referenced GitHub security advisory for details and workarounds.
CVE-2021-25283 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 7.5 HIGH 9.8 CRITICAL
An issue was discovered in through SaltStack Salt before 3002.5. The jinja renderer does not protect against server side template injection attacks.
CVE-2021-21332 2 Fedoraproject, Matrix 2 Fedora, Synapse 2021-11-23 4.3 MEDIUM 8.2 HIGH
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.27.0, the password reset endpoint served via Synapse was vulnerable to cross-site scripting (XSS) attacks. The impact depends on the configuration of the domain that Synapse is deployed on, but may allow access to cookies and other browser data, CSRF vulnerabilities, and access to other resources served on the same domain or parent domains. This is fixed in version 1.27.0.
CVE-2021-3144 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 7.5 HIGH 9.1 CRITICAL
In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. (They might be used to run command against the salt master or minions.)
CVE-2021-3148 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 7.5 HIGH 9.8 CRITICAL
An issue was discovered in SaltStack Salt before 3002.5. Sending crafted web requests to the Salt API can result in salt.utils.thin.gen_thin() command injection because of different handling of single versus double quotes. This is related to salt/utils/thin.py.
CVE-2020-28972 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 4.3 MEDIUM 5.9 MEDIUM
In SaltStack Salt before 3002.5, authentication to VMware vcenter, vsphere, and esxi servers (in the vmware.py files) does not always validate the SSL/TLS certificate.
CVE-2020-35662 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2021-11-23 5.8 MEDIUM 7.4 HIGH
In SaltStack Salt before 3002.5, when authenticating to services using certain modules, the SSL certificate is not always validated.
CVE-2021-21273 2 Fedoraproject, Matrix 2 Fedora, Synapse 2021-11-23 5.8 MEDIUM 6.1 MEDIUM
Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.25.0, requests to user provided domains were not restricted to external IP addresses when calculating the key validity for third-party invite events and sending push notifications. This could cause Synapse to make requests to internal infrastructure. The type of request was not controlled by the user, although limited modification of request bodies was possible. For the most thorough protection server administrators should remove the deprecated `federation_ip_range_blacklist` from their settings after upgrading to Synapse v1.25.0 which will result in Synapse using the improved default IP address restrictions. See the new `ip_range_blacklist` and `ip_range_whitelist` settings if more specific control is necessary.
CVE-2019-14462 3 Debian, Fedoraproject, Libmodbus 3 Debian Linux, Fedora, Libmodbus 2021-11-23 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in libmodbus before 3.0.7 and 3.1.x before 3.1.5. There is an out-of-bounds read for the MODBUS_FC_WRITE_MULTIPLE_COILS case, aka VD-1302.
CVE-2019-14463 3 Debian, Fedoraproject, Libmodbus 3 Debian Linux, Fedora, Libmodbus 2021-11-23 6.4 MEDIUM 9.1 CRITICAL
An issue was discovered in libmodbus before 3.0.7 and 3.1.x before 3.1.5. There is an out-of-bounds read for the MODBUS_FC_WRITE_MULTIPLE_REGISTERS case, aka VD-1301.
CVE-2021-30629 2 Fedoraproject, Google 2 Fedora, Chrome 2021-11-23 6.8 MEDIUM 8.8 HIGH
Use after free in Permissions in Google Chrome prior to 93.0.4577.82 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page.
