curl 7.20.0 through 7.70.0 is vulnerable to improper restriction of names for files and other resources that can lead too overwriting a local file when the -J flag is used.
CVE-2020-8231 5 Debian, Haxx, Oracle and 2 more 5 Debian Linux, Libcurl, Communications Cloud Native Core Policy and 2 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data.
CVE-2020-8285 9 Apple, Debian, Fedoraproject and 6 more 30 Mac Os X, Macos, Debian Linux and 27 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing.
CVE-2020-8286 8 Apple, Debian, Fedoraproject and 5 more 20 Mac Os X, Macos, Debian Linux and 17 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response.
CVE-2021-22876 8 Broadcom, Debian, Fedoraproject and 5 more 12 Fabric Operating System, Debian Linux, Fedora and 9 more 2024-03-27 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-2021-22890 8 Broadcom, Debian, Fedoraproject and 5 more 11 Fabric Operating System, Debian Linux, Fedora and 8 more 2024-03-27 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-2021-22898 6 Debian, Fedoraproject, Haxx and 3 more 12 Debian Linux, Fedora, Curl and 9 more 2024-03-27 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-2021-22946 8 Apple, Debian, Fedoraproject and 5 more 37 Macos, Debian Linux, Fedora and 34 more 2024-03-27 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-2021-22924 7 Debian, Fedoraproject, Haxx and 4 more 53 Debian Linux, Fedora, Libcurl and 50 more 2024-03-27 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-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2024-03-27 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-2021-22947 8 Apple, Debian, Fedoraproject and 5 more 34 Macos, Debian Linux, Fedora and 31 more 2024-03-27 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-2022-22576 5 Brocade, Debian, Haxx and 2 more 17 Fabric Operating System, Debian Linux, Curl and 14 more 2024-03-27 5.5 MEDIUM 8.1 HIGH
An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).
CVE-2022-27774 5 Brocade, Debian, Haxx and 2 more 17 Fabric Operating System, Debian Linux, Curl and 14 more 2024-03-27 3.5 LOW 5.7 MEDIUM
An insufficiently protected credentials vulnerability exists in curl 4.9 to and include curl 7.82.0 are affected that could allow an attacker to extract credentials when follows HTTP(S) redirects is used with authentication could leak credentials to other services that exist on different protocols or port numbers.
CVE-2022-27775 5 Brocade, Debian, Haxx and 2 more 17 Fabric Operating System, Debian Linux, Curl and 14 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
An information disclosure vulnerability exists in curl 7.65.0 to 7.82.0 are vulnerable that by using an IPv6 address that was in the connection pool but with a different zone id it could reuse a connection instead.
CVE-2022-27776 6 Brocade, Debian, Fedoraproject and 3 more 18 Fabric Operating System, Debian Linux, Fedora and 15 more 2024-03-27 4.3 MEDIUM 6.5 MEDIUM
A insufficiently protected credentials vulnerability in fixed in curl 7.83.0 might leak authentication or cookie header data on HTTP redirects to the same host but another port number.
CVE-2022-27781 4 Debian, Haxx, Netapp and 1 more 16 Debian Linux, Curl, Clustered Data Ontap and 13 more 2024-03-27 5.0 MEDIUM 7.5 HIGH
libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.
CVE-2022-27782 3 Debian, Haxx, Splunk 3 Debian Linux, Curl, Universal Forwarder 2024-03-27 5.0 MEDIUM 7.5 HIGH
libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.
CVE-2022-32205 7 Apple, Debian, Fedoraproject and 4 more 29 Macos, Debian Linux, Fedora and 26 more 2024-03-27 4.3 MEDIUM 4.3 MEDIUM
A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also would match for `bar.example.com`, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
CVE-2022-32206 6 Debian, Fedoraproject, Haxx and 3 more 30 Debian Linux, Fedora, Curl and 27 more 2024-03-27 4.3 MEDIUM 6.5 MEDIUM
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.
CVE-2022-32207 6 Apple, Debian, Fedoraproject and 3 more 19 Macos, Debian Linux, Fedora and 16 more 2024-03-27 7.5 HIGH 9.8 CRITICAL
When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.
