The GIF parser in ateimg32.dll in AOL Instant Messenger (AIM) 5.9.3797 and earlier allows remote attackers to cause a denial of service (crash) via a malformed buddy icon that causes an integer underflow in a loop counter variable.
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.
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-2016-8620 2 Haxx, Redhat 2 Curl, Rhel Software Collections 2026-04-15 N/A
The 'globbing' feature in curl before version 7.51.0 has a flaw that leads to integer overflow and out-of-bounds read via user controlled input.
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-2016-8622 2 Haxx, Redhat 3 Libcurl, Jboss Core Services, Rhel Software Collections 2026-04-15 N/A
The URL percent-encoding decode function in libcurl before 7.51.0 is called `curl_easy_unescape`. Internally, even if this function would be made to allocate a unscape destination buffer larger than 2GB, it would return that new length in a signed 32 bit integer variable, thus the length would get either just truncated or both truncated and turned negative. That could then lead to libcurl writing outside of its heap based buffer.
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.

Sandbox escape due to integer overflow in the Graphics component. This vulnerability was fixed in Firefox 147, Firefox ESR 115.32, Firefox ESR 140.7, Thunderbird 147, and Thunderbird 140.7.
CVE-2026-2762 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-04-15 9.8 Critical
Integer overflow in the JavaScript: Standard Library component. This vulnerability was fixed in Firefox 148, Firefox ESR 140.8, Thunderbird 148, and Thunderbird 140.8.
CVE-2026-27296 2 Adobe, Microsoft 2 Framemaker, Windows 2026-04-15 7.8 High
