CVE-2023-28322 4 Apple, Fedoraproject, Haxx and 1 more 13 Macos, Fedora, Curl and 10 more 2023-12-22 N/A 3.7 LOW
An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST.
CVE-2021-22924 6 Debian, Fedoraproject, Haxx and 3 more 52 Debian Linux, Fedora, Libcurl and 49 more 2022-07-28 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-2020-8284 8 Apple, Debian, Fedoraproject and 5 more 28 Mac Os X, Macos, Debian Linux and 25 more 2022-05-13 4.3 MEDIUM 3.7 LOW
A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.
CVE-2021-22898 5 Debian, Fedoraproject, Haxx and 2 more 11 Debian Linux, Fedora, Curl and 8 more 2022-05-13 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 5 Broadcom, Debian, Fedoraproject and 2 more 7 Fabric Operating System, Debian Linux, Fedora and 4 more 2021-07-20 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-2019-5435 1 Haxx 1 Curl 2020-10-20 4.3 MEDIUM 3.7 LOW
An integer overflow in curl's URL API results in a buffer overflow in libcurl 7.62.0 to and including 7.64.1.
CVE-2017-7407 1 Haxx 1 Curl 2019-10-03 2.1 LOW 2.4 LOW
The ourWriteOut function in tool_writeout.c in curl 7.53.1 might allow physically proximate attackers to obtain sensitive information from process memory in opportunistic circumstances by reading a workstation screen during use of a --write-out argument ending in a '%' character, which leads to a heap-based buffer over-read.
