CVE-2021-23437 2 Fedoraproject, Python 2 Fedora, Pillow 2024-11-21 5.0 MEDIUM 7.5 HIGH
The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) via the getrgb function.
CVE-2021-23414 2 Fedoraproject, Videojs 2 Fedora, Video.js 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
This affects the package video.js before 7.14.3. The src attribute of track tag allows to bypass HTML escaping and execute arbitrary code.
CVE-2021-23358 4 Debian, Fedoraproject, Tenable and 1 more 4 Debian Linux, Fedora, Tenable.sc and 1 more 2024-11-21 6.5 MEDIUM 3.3 LOW
The package underscore from 1.13.0-0 and before 1.13.0-2, from 1.3.2 and before 1.12.1 are vulnerable to Arbitrary Code Injection via the template function, particularly when a variable property is passed as an argument as it is not sanitized.
CVE-2021-23351 2 Fedoraproject, Go-proxyproto Project 2 Fedora, Go-proxyproto 2024-11-21 4.0 MEDIUM 4.4 MEDIUM
The package github.com/pires/go-proxyproto before 0.5.0 are vulnerable to Denial of Service (DoS) via the parseVersion1() function. The reader in this package is a default bufio.Reader wrapping a net.Conn. It will read from the connection until it finds a newline. Since no limits are implemented in the code, a deliberately malformed V1 header could be used to exhaust memory in a server process using this code - and create a DoS. This can be exploited by sending a stream starting with PROXY and continuing to send data (which does not contain a newline) until the target stops acknowledging. The risk here is small, because only trusted sources should be allowed to send proxy protocol headers.
CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2024-11-21 4.0 MEDIUM 5.9 MEDIUM
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
CVE-2021-23240 3 Fedoraproject, Netapp, Sudo Project 4 Fedora, Hci Management Node, Solidfire and 1 more 2024-11-21 4.4 MEDIUM 7.8 HIGH
selinux_edit_copy_tfiles in sudoedit in Sudo before 1.9.5 allows a local unprivileged user to gain file ownership and escalate privileges by replacing a temporary file with a symlink to an arbitrary file target. This affects SELinux RBAC support in permissive mode. Machines without SELinux are not vulnerable.
CVE-2021-23239 4 Debian, Fedoraproject, Netapp and 1 more 6 Debian Linux, Fedora, Cloud Backup and 3 more 2024-11-21 1.9 LOW 2.5 LOW
The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
CVE-2021-23215 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
CVE-2021-23214 3 Fedoraproject, Postgresql, Redhat 6 Fedora, Postgresql, Enterprise Linux and 3 more 2024-11-21 5.1 MEDIUM 8.1 HIGH
When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption.
CVE-2021-23177 4 Debian, Fedoraproject, Libarchive and 1 more 13 Debian Linux, Fedora, Libarchive and 10 more 2024-11-21 N/A 7.8 HIGH
An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges.
CVE-2021-23169 2 Fedoraproject, Openexr 2 Fedora, Openexr 2024-11-21 6.8 MEDIUM 8.8 HIGH
A heap-buffer overflow was found in the copyIntoFrameBuffer function of OpenEXR in versions before 3.0.1. An attacker could use this flaw to execute arbitrary code with the permissions of the user running the application compiled against OpenEXR.
CVE-2021-23134 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.6 MEDIUM 7.8 HIGH
Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability.
CVE-2021-23133 5 Broadcom, Debian, Fedoraproject and 2 more 24 Brocade Fabric Operating System, Debian Linux, Fedora and 21 more 2024-11-21 6.9 MEDIUM 6.7 MEDIUM
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
CVE-2021-23017 5 F5, Fedoraproject, Netapp and 2 more 13 Nginx, Fedora, Ontap Select Deploy Administration Utility and 10 more 2024-11-21 6.8 MEDIUM 7.7 HIGH
A security issue in nginx resolver was identified, which might allow an attacker who is able to forge UDP packets from the DNS server to cause 1-byte memory overwrite, resulting in worker process crash or potential other impact.
CVE-2021-22947 8 Apple, Debian, Fedoraproject and 5 more 34 Macos, Debian Linux, Fedora and 31 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.
CVE-2021-22946 8 Apple, Debian, Fedoraproject and 5 more 37 Macos, Debian Linux, Fedora and 34 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2024-11-21 5.8 MEDIUM 9.1 CRITICAL
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
CVE-2021-22925 7 Apple, Fedoraproject, Haxx and 4 more 27 Mac Os X, Macos, Fedora and 24 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
curl supports the `-t` command line option, known as `CURLOPT_TELNETOPTIONS`in libcurl. This rarely used option is used to send variable=content pairs toTELNET servers.Due to flaw in the option parser for sending `NEW_ENV` variables, libcurlcould be made to pass on uninitialized data from a stack based buffer to theserver. Therefore potentially revealing sensitive internal information to theserver using a clear-text network protocol.This could happen because curl did not call and use sscanf() correctly whenparsing the string provided by the application.
CVE-2021-22924 7 Debian, Fedoraproject, Haxx and 4 more 53 Debian Linux, Fedora, Libcurl and 50 more 2024-11-21 4.3 MEDIUM 3.7 LOW
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2021-22923 6 Fedoraproject, Haxx, Netapp and 3 more 23 Fedora, Curl, Cloud Backup and 20 more 2024-11-21 2.6 LOW 5.3 MEDIUM
When curl is instructed to get content using the metalink feature, and a user name and password are used to download the metalink XML file, those same credentials are then subsequently passed on to each of the servers from which curl will download or try to download the contents from. Often contrary to the user's expectations and intentions and without telling the user it happened.
