Integer overflow in the SCTP_SOCKOPT_DEBUG_NAME SCTP socket option in socket.c in the Linux kernel 2.4.25 and earlier allows local users to execute arbitrary code via an optlen value of -1, which causes kmalloc to allocate 0 bytes of memory.

Off-by-one vulnerability in CPIA driver of Linux kernel before 2.2.19 allows users to modify kernel memory.
CVE-2006-3198 1 Opera 1 Opera Browser 2026-04-16 N/A
Integer overflow in Opera 8.54 and earlier allows remote attackers to execute arbitrary code via a JPEG image with large height and width values, which causes less memory to be allocated than intended.
CVE-2004-0788 2 Gnome, Redhat 3 Gdkpixbuf, Gtk, Enterprise Linux 2026-04-16 N/A
Integer overflow in the ICO image decoder for (1) gdk-pixbuf before 0.22 and (2) gtk2 before 2.2.4 allows remote attackers to cause a denial of service (application crash) via a crafted ICO file.
CVE-2003-0625 1 Hadrons 1 Xfstt 2026-04-16 7.5 High
Off-by-one error in certain versions of xfstt allows remote attackers to read potentially sensitive memory via a malformed client request in the connection handshake, which leaks the memory in the server's response.
CVE-2004-0005 1 Gaim Project 1 Gaim 2026-04-16 9.8 Critical
Multiple buffer overflows in Gaim 0.75 allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) octal encoding in yahoo_decode that causes a null byte to be written beyond the buffer, (2) octal encoding in yahoo_decode that causes a pointer to reference memory beyond the terminating null byte, (3) a quoted printable string to the gaim_quotedp_decode MIME decoder that causes a null byte to be written beyond the buffer, and (4) quoted printable encoding in gaim_quotedp_decode that causes a pointer to reference memory beyond the terminating null byte.
CVE-2005-0199 1 Barton 1 Ngircd 2026-04-16 9.8 Critical
Integer underflow in the Lists_MakeMask() function in lists.c in ngIRCd before 0.8.2 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long MODE line that causes an incorrect length calculation, which leads to a buffer overflow.
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.
CVE-2026-0880 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-04-15 8.8 High
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.
