CVE-2003-0552 1 Redhat 2 Enterprise Linux, Linux 2026-04-16 N/A
Linux 2.4.x allows remote attackers to spoof the bridge Forwarding table via forged packets whose source addresses are the same as the target.
CVE-2026-2239 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-04-15 2.8 Low
A flaw was found in GIMP. Heap-buffer-overflow vulnerability exists in the fread_pascal_string function when processing a specially crafted PSD (Photoshop Document) file. This occurs because the buffer allocated for a Pascal string is not properly null-terminated, leading to an out-of-bounds read when strlen() is subsequently called. Successfully exploiting this vulnerability can cause the application to crash, resulting in an application level Denial of Service.
CVE-2020-8177 6 Debian, Fujitsu, Haxx and 3 more 19 Debian Linux, M10-1, M10-1 Firmware and 16 more 2026-04-15 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-2020-27153 4 Bluez, Debian, Opensuse and 1 more 4 Bluez, Debian Linux, Leap and 1 more 2026-04-15 8.6 High
In BlueZ before 5.55, a double free was found in the gatttool disconnect_cb() routine from shared/att.c. A remote attacker could potentially cause a denial of service or code execution, during service discovery, due to a redundant disconnect MGMT event.
CVE-2019-5482 7 Debian, Fedoraproject, Haxx and 4 more 24 Debian Linux, Fedora, Curl and 21 more 2026-04-15 9.8 Critical
Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3.
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-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-2017-1000257 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-2018-16842 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-2024-21823 1 Redhat 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more 2026-04-15 7.5 High
Hardware logic with insecure de-synchronization in Intel(R) DSA and Intel(R) IAA for some Intel(R) 4th or 5th generation Xeon(R) processors may allow an authorized user to potentially enable escalation of privilege local access
CVE-2024-23185 1 Redhat 2 Enterprise Linux, Rhel Eus 2026-04-15 7.5 High
Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "full_value" buffer out of the smaller chunks. The full_value buffer has no size limit, so large headers can cause large memory usage. It doesn't matter whether it's a single long header line, or a single header split into multiple lines. This bug exists in all Dovecot versions. Incoming mails typically have some size limits set by MTA, so even largest possible header size may still fit into Dovecot's vsz_limit. So attackers probably can't DoS a victim user this way. A user could APPEND larger mails though, allowing them to DoS themselves (although maybe cause some memory issues for the backend in general). One can implement restrictions on headers on MTA component preceding Dovecot. No publicly available exploits are known.
CVE-2024-4076 2 Isc, Redhat 7 Bind, Enterprise Linux, Openshift and 4 more 2026-04-15 7.5 High
Client queries that trigger serving stale data and that also require lookups in local authoritative zone data may result in an assertion failure. This issue affects BIND 9 versions 9.16.13 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.33-S1 through 9.11.37-S1, 9.16.13-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.27-S1.
