CVE-2021-22922 6 Fedoraproject, Haxx, Netapp and 3 more 23 Fedora, Curl, Cloud Backup and 20 more 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
When curl is instructed to download content using the metalink feature, thecontents is verified against a hash provided in the metalink XML file.The metalink XML file points out to the client how to get the same contentfrom a set of different URLs, potentially hosted by different servers and theclient can then download the file from one or several of them. In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload. It should remove the contents and instead try getting the contentsfrom another URL. This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk.
CVE-2021-22915 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2024-11-21 5.0 MEDIUM 9.8 CRITICAL
Nextcloud server before 19.0.11, 20.0.10, 21.0.2 is vulnerable to brute force attacks due to lack of inclusion of IPv6 subnets in rate-limiting considerations. This could potentially result in an attacker bypassing rate-limit controls such as the Nextcloud brute-force protection.
CVE-2021-22898 6 Debian, Fedoraproject, Haxx and 3 more 12 Debian Linux, Fedora, Curl and 9 more 2024-11-21 2.6 LOW 3.1 LOW
curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol.
CVE-2021-22890 8 Broadcom, Debian, Fedoraproject and 5 more 11 Fabric Operating System, Debian Linux, Fedora and 8 more 2024-11-21 4.3 MEDIUM 3.7 LOW
curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
CVE-2021-22884 5 Fedoraproject, Netapp, Nodejs and 2 more 13 Fedora, Active Iq Unified Manager, E-series Performance Analyzer and 10 more 2024-11-21 5.1 MEDIUM 7.5 HIGH
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in CVE-2018-7160.
CVE-2021-22883 5 Fedoraproject, Netapp, Nodejs and 2 more 9 Fedora, E-series Performance Analyzer, Node.js and 6 more 2024-11-21 7.8 HIGH 7.5 HIGH
Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to a denial of service attack when too many connection attempts with an 'unknownProtocol' are established. This leads to a leak of file descriptors. If a file descriptor limit is configured on the system, then the server is unable to accept new connections and prevent the process also from opening, e.g. a file. If no file descriptor limit is configured, then this lead to an excessive memory usage and cause the system to run out of memory.
CVE-2021-22881 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2024-11-21 5.8 MEDIUM 6.1 MEDIUM
The Host Authorization middleware in Action Pack before 6.1.2.1, 6.0.3.5 suffers from an open redirect vulnerability. Specially crafted `Host` headers in combination with certain "allowed host" formats can cause the Host Authorization middleware in Action Pack to redirect users to a malicious website. Impacted applications will have allowed hosts with a leading dot. When an allowed host contains a leading dot, a specially crafted `Host` header can be used to redirect to a malicious website.
CVE-2021-22880 2 Fedoraproject, Rubyonrails 2 Fedora, Rails 2024-11-21 5.0 MEDIUM 7.5 HIGH
The PostgreSQL adapter in Active Record before 6.1.2.1, 6.0.3.5, 5.2.4.5 suffers from a regular expression denial of service (REDoS) vulnerability. Carefully crafted input can cause the input validation in the `money` type of the PostgreSQL adapter in Active Record to spend too much time in a regular expression, resulting in the potential for a DoS attack. This only impacts Rails applications that are using PostgreSQL along with money type columns that take user input.
CVE-2021-22879 2 Fedoraproject, Nextcloud 2 Fedora, Desktop 2024-11-21 6.8 MEDIUM 8.8 HIGH
Nextcloud Desktop Client prior to 3.1.3 is vulnerable to resource injection by way of missing validation of URLs, allowing a malicious server to execute remote commands. User interaction is needed for exploitation.
CVE-2021-22878 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2024-11-21 3.5 LOW 4.8 MEDIUM
Nextcloud Server prior to 20.0.6 is vulnerable to reflected cross-site scripting (XSS) due to lack of sanitization in `OC.Notification.show`.
CVE-2021-22877 2 Fedoraproject, Nextcloud 2 Fedora, Nextcloud Server 2024-11-21 5.5 MEDIUM 6.5 MEDIUM
A missing user check in Nextcloud prior to 20.0.6 inadvertently populates a user's own credentials for other users external storage configuration when not already configured yet.
CVE-2021-22876 8 Broadcom, Debian, Fedoraproject and 5 more 12 Fabric Operating System, Debian Linux, Fedora and 9 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
curl 7.1.1 to and including 7.75.0 is vulnerable to an "Exposure of Private Personal Information to an Unauthorized Actor" by leaking credentials in the HTTP Referer: header. libcurl does not strip off user credentials from the URL when automatically populating the Referer: HTTP request header field in outgoing HTTP requests, and therefore risks leaking sensitive data to the server that is the target of the second HTTP request.
CVE-2021-22570 5 Debian, Fedoraproject, Google and 2 more 8 Debian Linux, Fedora, Protobuf and 5 more 2024-11-21 2.1 LOW 6.5 MEDIUM
Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater.
CVE-2021-22543 4 Debian, Fedoraproject, Linux and 1 more 21 Debian Linux, Fedora, Linux Kernel and 18 more 2024-11-21 4.6 MEDIUM 7.8 HIGH
An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation.
CVE-2021-22212 2 Fedoraproject, Ntpsec 2 Fedora, Ntpsec 2024-11-21 5.8 MEDIUM 4.0 MEDIUM
ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with '#' characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the '#'. This results in the administrator not being able to use the keys as expected or the keys are shorter than expected and easier to brute-force, possibly resulting in MITM attacks between ntp clients and ntp servers. For short AES128 keys, ntpd generates a warning that it is padding them.
CVE-2021-22207 4 Debian, Fedoraproject, Oracle and 1 more 4 Debian Linux, Fedora, Zfs Storage Appliance Kit and 1 more 2024-11-21 5.0 MEDIUM 5.5 MEDIUM
