CVE-2021-22925 8 Apple, Fedoraproject, Haxx and 5 more 28 Mac Os X, Macos, Fedora and 25 more 2026-04-16 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-2021-22947 9 Apple, Debian, Fedoraproject and 6 more 37 Macos, Debian Linux, Fedora and 34 more 2026-04-16 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 9 Apple, Debian, Fedoraproject and 6 more 40 Macos, Debian Linux, Fedora and 37 more 2026-04-16 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-2021-22922 7 Fedoraproject, Haxx, Netapp and 4 more 25 Fedora, Curl, Cloud Backup and 22 more 2026-04-16 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-2020-8285 10 Apple, Debian, Fedoraproject and 7 more 32 Mac Os X, Macos, Debian Linux and 29 more 2026-04-16 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-2020-8284 10 Apple, Debian, Fedoraproject and 7 more 31 Mac Os X, Macos, Debian Linux and 28 more 2026-04-16 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-2019-5481 7 Debian, Fedoraproject, Haxx and 4 more 15 Debian Linux, Fedora, Curl and 12 more 2026-04-16 9.8 Critical
Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.
CVE-2021-22898 7 Debian, Fedoraproject, Haxx and 4 more 13 Debian Linux, Fedora, Curl and 10 more 2026-04-16 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-2004-0986 4 Debian, Linux, Redhat and 1 more 4 Debian Linux, Linux Kernel, Fedora Core and 1 more 2026-04-16 N/A
Iptables before 1.2.11, under certain conditions, does not properly load the required modules at system startup, which causes the firewall rules to fail to load and protect the system from remote attackers.
CVE-2004-0595 4 Avaya, Php, Redhat and 1 more 11 Converged Communications Server, Integrated Management, S8300 and 8 more 2026-04-16 N/A
The strip_tags function in PHP 4.x up to 4.3.7, and 5.x up to 5.0.0RC3, does not filter null (\0) characters within tag names when restricting input to allowed tags, which allows dangerous tags to be processed by web browsers such as Internet Explorer and Safari, which ignore null characters and facilitate the exploitation of cross-site scripting (XSS) vulnerabilities.
CVE-2004-0903 4 Conectiva, Mozilla, Redhat and 1 more 9 Linux, Mozilla, Thunderbird and 6 more 2026-04-16 N/A
Stack-based buffer overflow in the writeGroup function in nsVCardObj.cpp for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to execute arbitrary code via malformed VCard attachments that are not properly handled when previewing a message.
CVE-2004-0461 5 Infoblox, Isc, Mandrakesoft and 2 more 11 Dns One Appliance, Dhcpd, Mandrake Linux and 8 more 2026-04-16 N/A
The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.
CVE-2004-0802 9 Conectiva, Enlightenment, Imagemagick and 6 more 16 Linux, Imlib, Imlib2 and 13 more 2026-04-16 N/A
Buffer overflow in the BMP loader in imlib2 before 1.1.2 allows remote attackers to execute arbitrary code via a specially-crafted BMP image, a different vulnerability than CVE-2004-0817.
CVE-2004-0961 2 Freeradius, Redhat 3 Freeradius, Enterprise Linux, Fedora Core 2026-04-16 N/A

CVE-2004-1012 6 Carnegie Mellon University, Conectiva, Openpkg and 3 more 6 Cyrus Imap Server, Linux, Openpkg and 3 more 2026-04-16 N/A
The argument parser of the PARTIAL command in Cyrus IMAP Server 2.2.6 and earlier allows remote authenticated users to execute arbitrary code via a certain command ("body[p") that is treated as a different command ("body.peek") and causes an index increment error that leads to an out-of-bounds memory corruption.
CVE-2004-0883 5 Linux, Redhat, Suse and 2 more 8 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 5 more 2026-04-16 N/A
Multiple vulnerabilities in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 allow remote samba servers to cause a denial of service (crash) or gain sensitive information from kernel memory via a samba server (1) returning more data than requested to the smb_proc_read function, (2) returning a data offset from outside the samba packet to the smb_proc_readX function, (3) sending a certain TRANS2 fragmented packet to the smb_receive_trans2 function, (4) sending a samba packet with a certain header size to the smb_proc_readX_data function, or (5) sending a certain packet based offset for the data in a packet to the smb_receive_trans2 function.
CVE-2004-0415 3 Linux, Redhat, Trustix 4 Linux Kernel, Enterprise Linux, Fedora Core and 1 more 2026-04-16 N/A
Linux kernel does not properly convert 64-bit file offset pointers to 32 bits, which allows local users to access portions of kernel memory.
