CVE-2008-3281 7 Apple, Canonical, Debian and 4 more 12 Iphone Os, Safari, Ubuntu Linux and 9 more 2026-04-23 6.5 Medium
libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
CVE-2007-5191 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-04-23 N/A
mount and umount in util-linux and loop-aes-utils call the setuid and setgid functions in the wrong order and do not check the return values, which might allow attackers to gain privileges via helpers such as mount.nfs.
CVE-2007-4000 3 Fedoraproject, Mit, Redhat 3 Fedora, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.
CVE-2008-3969 2 Bitlbee, Fedoraproject 2 Bitlbee, Fedora 2026-04-23 N/A
Multiple unspecified vulnerabilities in BitlBee before 1.2.3 allow remote attackers to "overwrite" and "hijack" existing accounts via unknown vectors related to "inconsistent handling of the USTATUS_IDENTIFIED state." NOTE: this issue exists because of an incomplete fix for CVE-2008-3920.
CVE-2007-3304 4 Apache, Canonical, Fedoraproject and 1 more 11 Http Server, Ubuntu Linux, Fedora and 8 more 2026-04-23 N/A
Apache httpd 1.3.37, 2.0.59, and 2.2.4 with the Prefork MPM module, allows local users to cause a denial of service by modifying the worker_score and process_score arrays to reference an arbitrary process ID, which is sent a SIGUSR1 signal from the master process, aka "SIGUSR1 killer."
CVE-2008-2944 3 Fedoraproject, Linux, Redhat 3 Fedora Core, Linux Kernel, Enterprise Linux 2026-04-23 N/A
Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU GDB testsuite, a different vulnerability than CVE-2008-2365.
CVE-2008-2951 2 Edgewall, Fedoraproject 2 Trac, Fedora 2026-04-23 6.1 Medium
Open redirect vulnerability in the search script in Trac before 0.10.5 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the q parameter, possibly related to the quickjump function.
CVE-2012-1823 8 Apple, Debian, Fedoraproject and 5 more 20 Mac Os X, Debian Linux, Fedora and 17 more 2026-04-21 9.8 Critical
sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case.
CVE-2014-0160 13 Broadcom, Canonical, Debian and 10 more 37 Symantec Messaging Gateway, Ubuntu Linux, Debian Linux and 34 more 2026-04-21 7.5 High
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.
CVE-2016-5195 7 Canonical, Debian, Fedoraproject and 4 more 24 Ubuntu Linux, Debian Linux, Fedora and 21 more 2026-04-21 7.0 High
Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW."
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-2005-2970 4 Apache, Canonical, Fedoraproject and 1 more 7 Http Server, Ubuntu Linux, Fedora Core and 4 more 2026-04-16 N/A
Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.
CVE-2022-0204 3 Bluez, Debian, Fedoraproject 3 Bluez, Debian Linux, Fedora 2026-04-15 8.8 High
A heap overflow vulnerability was found in bluez in versions prior to 5.63. An attacker with local network access could pass specially crafted files causing an application to halt or crash, leading to a denial of service.
