CVE-2019-5436 8 Debian, F5, Fedoraproject and 5 more 15 Debian Linux, Traffix Signaling Delivery Controller, Fedora and 12 more 2026-04-15 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-2019-12098 4 Debian, Fedoraproject, Heimdal Project and 1 more 5 Debian Linux, Fedora, Heimdal and 2 more 2026-04-15 7.4 High
In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c.
CVE-2018-1000301 5 Canonical, Debian, Haxx and 2 more 15 Ubuntu Linux, Debian Linux, Curl and 12 more 2026-04-15 9.1 Critical
curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content.. This vulnerability appears to have been fixed in curl < 7.20.0 and curl >= 7.60.0.
CVE-2017-8817 3 Debian, Haxx, Redhat 4 Debian Linux, Curl, Libcurl and 1 more 2026-04-15 9.8 Critical
The FTP wildcard function in curl and libcurl before 7.57.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a string that ends with an '[' character.
CVE-2017-8816 3 Debian, Haxx, Redhat 4 Debian Linux, Curl, Libcurl and 1 more 2026-04-15 9.8 Critical
The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields.
CVE-2017-1000257 3 Debian, Haxx, Redhat 5 Debian Linux, Libcurl, Enterprise Linux and 2 more 2026-04-15 9.1 Critical
An IMAP FETCH response line indicates the size of the returned data, in number of bytes. When that response says the data is zero bytes, libcurl would pass on that (non-existing) data with a pointer and the size (zero) to the deliver-data function. libcurl's deliver-data function treats zero as a magic number and invokes strlen() on the data to figure out the length. The strlen() is called on a heap based buffer that might not be zero terminated so libcurl might read beyond the end of it into whatever memory lies after (or just crash) and then deliver that to the application as if it was actually downloaded.
CVE-2018-16839 4 Canonical, Debian, Haxx and 1 more 4 Ubuntu Linux, Debian Linux, Curl and 1 more 2026-04-15 N/A
Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.
CVE-2018-16842 4 Canonical, Debian, Haxx and 1 more 6 Ubuntu Linux, Debian Linux, Curl and 3 more 2026-04-15 N/A
Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.
CVE-2018-14618 4 Canonical, Debian, Haxx and 1 more 6 Ubuntu Linux, Debian Linux, Libcurl and 3 more 2026-04-15 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-2018-16890 8 Canonical, Debian, F5 and 5 more 11 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 8 more 2026-04-15 7.5 High
libcurl versions from 7.36.0 to before 7.64.0 is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.
CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 17 Ubuntu Linux, Debian Linux, Libcurl and 14 more 2026-04-15 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-2019-3823 6 Canonical, Debian, Haxx and 3 more 9 Ubuntu Linux, Debian Linux, Libcurl and 6 more 2026-04-15 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-2019-16738 3 Debian, Fedoraproject, Mediawiki 3 Debian Linux, Fedora, Mediawiki 2026-04-15 5.3 Medium
In MediaWiki through 1.33.0, Special:Redirect allows information disclosure of suppressed usernames via a User ID Lookup.
CVE-2021-3910 2 Cloudflare, Debian 2 Octorpki, Debian Linux 2026-04-15 4.4 Medium
OctoRPKI crashes when encountering a repository that returns an invalid ROA (just an encoded NUL (\0) character).
CVE-2025-62672 2 Boyns, Debian 2 Rplay, Debian Linux 2026-04-15 5.3 Medium
rplay through 3.3.2 allows attackers to cause a denial of service (SIGSEGV and daemon crash) or possibly have unspecified other impact. This occurs in memcpy in the RPLAY_DATA case in rplay_unpack in librplay/rplay.c, potentially reachable via packet data with no authentication.
CVE-2020-26147 5 Arista, Debian, Linux and 2 more 15 C-65, C-65 Firmware, C-75 and 12 more 2026-04-14 5.4 Medium
An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP, CCMP, or GCMP data-confidentiality protocol is used.
CVE-2020-26139 6 Arista, Cisco, Debian and 3 more 331 C-100, C-100 Firmware, C-110 and 328 more 2026-04-14 5.3 Medium
An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other clients even though the sender has not yet successfully authenticated to the AP. This might be abused in projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier to exploit other vulnerabilities in connected clients.
CVE-2020-24588 9 Arista, Cisco, Debian and 6 more 351 C-100, C-100 Firmware, C-110 and 348 more 2026-04-14 3.5 Low
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
CVE-2020-11022 9 Debian, Drupal, Fedoraproject and 6 more 88 Debian Linux, Drupal, Fedora and 85 more 2026-04-13 6.9 Medium
In jQuery starting with 1.12.0 and before 3.5.0, passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code. This problem is patched in jQuery 3.5.0.
CVE-2024-44986 2 Debian, Linux 2 Debian Linux, Linux Kernel 2026-04-09 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible UAF in ip6_finish_output2() If skb_expand_head() returns NULL, skb has been freed and associated dst/idev could also have been freed. We need to hold rcu_read_lock() to make sure the dst and associated idev are alive.
