CVE-2018-14618 4 Canonical, Debian, Haxx and 1 more 6 Ubuntu Linux, Debian Linux, Libcurl and 3 more 2024-08-05 N/A
curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)
CVE-2018-0500 3 Canonical, Haxx, Redhat 3 Ubuntu Linux, Curl, Jboss Core Services 2024-08-05 N/A
Curl_smtp_escape_eob in lib/smtp.c in curl 7.54.1 to and including curl 7.60.0 has a heap-based buffer overflow that might be exploitable by an attacker who can control the data that curl transmits over SMTP with certain settings (i.e., use of a nonstandard --limit-rate argument or CURLOPT_BUFFERSIZE value).
CVE-2019-5482 7 Debian, Fedoraproject, Haxx and 4 more 24 Debian Linux, Fedora, Curl and 21 more 2024-08-04 9.8 Critical
Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3.
CVE-2019-5443 4 Haxx, Microsoft, Netapp and 1 more 10 Curl, Windows, Oncommand Insight and 7 more 2024-08-04 7.8 High
A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl "engine") on invocation. If that curl is invoked by a privileged user it can do anything it wants.
CVE-2019-5481 7 Debian, Fedoraproject, Haxx and 4 more 15 Debian Linux, Fedora, Curl and 12 more 2024-08-04 9.8 Critical
Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.
CVE-2019-5435 2 Haxx, Redhat 2 Curl, Jboss Core Services 2024-08-04 N/A
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-2019-5436 8 Debian, F5, Fedoraproject and 5 more 15 Debian Linux, Traffix Signaling Delivery Controller, Fedora and 12 more 2024-08-04 7.8 High
A heap buffer overflow in the TFTP receiving code allows for DoS or arbitrary code execution in libcurl versions 7.19.4 through 7.64.1.
CVE-2019-3823 6 Canonical, Debian, Haxx and 3 more 9 Ubuntu Linux, Debian Linux, Libcurl and 6 more 2024-08-04 N/A
libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 17 Ubuntu Linux, Debian Linux, Libcurl and 14 more 2024-08-04 9.8 Critical
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2020-19909 1 Haxx 1 Curl 2024-08-04 3.3 Low
Integer overflow vulnerability in tool_operate.c in curl 7.65.2 via a large value as the retry delay. NOTE: many parties report that this has no direct security impact on the curl user; however, it may (in theory) cause a denial of service to associated systems or networks if, for example, --retry-delay is misinterpreted as a value much smaller than what was intended. This is not especially plausible because the overflow only happens if the user was trying to specify that curl should wait weeks (or longer) before trying to recover from a transient error.
CVE-2020-8286 9 Apple, Debian, Fedoraproject and 6 more 22 Mac Os X, Macos, Debian Linux and 19 more 2024-08-04 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-2020-8284 10 Apple, Debian, Fedoraproject and 7 more 31 Mac Os X, Macos, Debian Linux and 28 more 2024-08-04 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-2020-8285 10 Apple, Debian, Fedoraproject and 7 more 32 Mac Os X, Macos, Debian Linux and 29 more 2024-08-04 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-2020-8231 6 Debian, Haxx, Oracle and 3 more 6 Debian Linux, Libcurl, Communications Cloud Native Core Policy and 3 more 2024-08-04 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-2020-8177 6 Debian, Fujitsu, Haxx and 3 more 19 Debian Linux, M10-1, M10-1 Firmware and 16 more 2024-08-04 7.8 High
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-2020-8169 5 Debian, Haxx, Redhat and 2 more 7 Debian Linux, Curl, Jboss Core Services and 4 more 2024-08-04 7.5 High
curl 7.62.0 through 7.70.0 is vulnerable to an information disclosure vulnerability that can lead to a partial password being leaked over the network and to the DNS server(s).
CVE-2021-22947 9 Apple, Debian, Fedoraproject and 6 more 37 Macos, Debian Linux, Fedora and 34 more 2024-08-03 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-2021-22923 7 Fedoraproject, Haxx, Netapp and 4 more 25 Fedora, Curl, Cloud Backup and 22 more 2024-08-03 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.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2024-08-03 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-2021-22946 9 Apple, Debian, Fedoraproject and 6 more 40 Macos, Debian Linux, Fedora and 37 more 2024-08-03 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.
