| 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-2021-23133 | 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-2021-22947 | 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*. | |||||

| 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. | |||||

| 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. | |||||
| 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-2021-22901 | 5 Haxx, Netapp, Oracle and 2 more | 34 Curl, Active Iq Unified Manager, Cloud Backup and 31 more | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory. | |||||
| CVE-2021-22897 | 5 Haxx, Netapp, Oracle and 2 more | 30 Curl, Cloud Backup, H300e and 27 more | 2024-11-21 | 4.3 MEDIUM | 5.3 MEDIUM |
| curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. | |||||
| 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-2021-20284 | 2 Gnu, Netapp | 3 Binutils, Cloud Backup, Ontap Select Deploy Administration Utility | 2024-11-21 | 4.3 MEDIUM | 5.5 MEDIUM |
| A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-20226 | 2 Linux, Netapp | 2 Linux Kernel, Cloud Backup | 2024-11-21 | 6.1 MEDIUM | 7.8 HIGH |
| A use-after-free flaw was found in the io_uring in Linux kernel, where a local attacker with a user privilege could cause a denial of service problem on the system The issue results from the lack of validating the existence of an object prior to performing operations on the object by not incrementing the file reference counter while in use. The highest threat from this vulnerability is to data integrity, confidentiality and system availability. | |||||

| There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink. | |||||
