CVE-2026-40394 2 Varnish-software, Vinyl-cache 3 Varnish Cache, Varnish Enterprise, Vinyl Cache 2026-04-17 4 Medium
Varnish Cache 9 before 9.0.1 and Varnish Enterprise before 6.0.16r11 allows a "workspace overflow" denial of service (daemon panic) for certain amounts of prefetched data. The setup of an HTTP/2 session starts with a speculative HTTP/1 transport, and upon upgrading to h2 the HTTP/1 request is repurposed as stream zero. During the upgrade, a buffer allocation is made to reserve space to send frames to the client. This allocation would split the original workspace, and depending on the amount of prefetched data, the next fetch could perform a pipelining operation that would run out of workspace.
CVE-2026-20049 1 Cisco 3 Adaptive Security Appliance Software, Firepower Threat Defense Software, Secure Firewall Threat Defense 2026-04-17 7.7 High
A vulnerability in the processing of Galois/Counter Mode (GCM)-encrypted Internet Key Exchange version 2 (IKEv2) IPsec traffic of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to the allocation of an insufficiently sized block of memory. An attacker could exploit this vulnerability by sending crafted GCM-encrypted IPsec traffic to an affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition. To exploit this vulnerability, the attacker must have valid credentials to establish a VPN connection with the affected device.
CVE-2018-25244 1 Ecosearch 1 Eco Search 2026-04-16 6.2 Medium
Eco Search 1.0.2.0 contains a denial of service vulnerability that allows local attackers to crash the application by submitting an excessively long string to the search functionality. Attackers can paste a buffer of 950 or more characters into the search bar and trigger a crash by initiating a search operation.
CVE-2026-28686 1 Imagemagick 1 Imagemagick 2026-04-16 6.8 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, A heap-buffer-overflow vulnerability exists in the PCL encode due to an undersized output buffer allocation. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
CVE-2001-0248 2 Hp, Sgi 2 Hp-ux, Irix 2026-04-16 9.8 Critical
Buffer overflow in FTP server in HPUX 11 allows remote attackers to execute arbitrary commands by creating a long pathname and calling the STAT command, which uses glob to generate long strings.
CVE-2001-0334 1 Microsoft 1 Internet Information Server 2026-04-16 7.5 High
FTP service in IIS 5.0 and earlier allows remote attackers to cause a denial of service via a wildcard sequence that generates a long string when it is expanded.
CVE-2002-1347 3 Apple, Cyrusimap, Redhat 4 Mac Os X, Mac Os X Server, Cyrus Sasl and 1 more 2026-04-16 9.8 Critical
Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string.
CVE-2002-0184 3 Debian, Redhat, Sudo Project 4 Debian Linux, Linux, Powertools and 1 more 2026-04-16 7.8 High
Sudo before 1.6.6 contains an off-by-one error that can result in a heap-based buffer overflow that may allow local users to gain root privileges via special characters in the -p (prompt) argument, which are not properly expanded.
CVE-2004-1363 1 Oracle 7 Application Server, Collaboration Suite, Database Server and 4 more 2026-04-16 9.8 Critical
Buffer overflow in extproc in Oracle 10g allows remote attackers to execute arbitrary code via environment variables in the library name, which are expanded after the length check is performed.
CVE-2001-0249 3 Hp, Oracle, Sgi 3 Hp-ux, Solaris, Irix 2026-04-16 9.8 Critical
Heap overflow in FTP daemon in Solaris 8 allows remote attackers to execute arbitrary commands by creating a long pathname and calling the LIST command, which uses glob to generate long strings.
CVE-2005-3120 3 Debian, Invisible-island, Redhat 3 Debian Linux, Lynx, Enterprise Linux 2026-04-16 9.8 Critical
Stack-based buffer overflow in the HTrjis function in Lynx 2.8.6 and earlier allows remote NNTP servers to execute arbitrary code via certain article headers containing Asian characters that cause Lynx to add extra escape (ESC) characters.
CVE-2004-0940 7 Apache, Hp, Openpkg and 4 more 9 Http Server, Hp-ux, Openpkg and 6 more 2026-04-16 7.8 High
Buffer overflow in the get_tag function in mod_include for Apache 1.3.x to 1.3.32 allows local users who can create SSI documents to execute arbitrary code as the apache user via SSI (XSSI) documents that trigger a length calculation error.
CVE-2003-0899 1 Acme 1 Thttpd 2026-04-16 9.8 Critical
Buffer overflow in defang in libhttpd.c for thttpd 2.21 to 2.23b1 allows remote attackers to execute arbitrary code via requests that contain '<' or '>' characters, which trigger the overflow when the characters are expanded to "&lt;" and "&gt;" sequences.
CVE-2004-0747 2 Apache, Redhat 2 Http Server, Enterprise Linux 2026-04-16 7.8 High
Buffer overflow in Apache 2.0.50 and earlier allows local users to gain apache privileges via a .htaccess file that causes the overflow during expansion of environment variables.
CVE-2005-2103 2 Gaim Project, Redhat 2 Gaim, Enterprise Linux 2026-04-16 9.8 Critical
Buffer overflow in the AIM and ICQ module in Gaim before 1.5.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an away message with a large number of AIM substitution strings, such as %t or %n.
CVE-2005-0490 2 Haxx, Redhat 3 Curl, Libcurl, Enterprise Linux 2026-04-16 8.8 High
Multiple stack-based buffer overflows in libcURL and cURL 7.12.1, and possibly other versions, allow remote malicious web servers to execute arbitrary code via base64 encoded replies that exceed the intended buffer lengths when decoded, which is not properly handled by (1) the Curl_input_ntlm function in http_ntlm.c during NTLM authentication or (2) the Curl_krb_kauth and krb4_auth functions in krb4.c during Kerberos authentication.
CVE-2004-0434 2 Debian, Heimdal Project 2 Debian Linux, Heimdal 2026-04-16 9.8 Critical
k5admind (kadmind) for Heimdal allows remote attackers to execute arbitrary code via a Kerberos 4 compatibility administration request whose framing length is less than 2, which leads to a heap-based buffer overflow.
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-2026-34743 2 Tukaani, Tukaani-project 2 Xz, Xz 2026-04-15 5.3 Medium
XZ Utils provide a general-purpose data-compression library plus command-line tools. Prior to version 5.8.3, if lzma_index_decoder() was used to decode an Index that contained no Records, the resulting lzma_index was left in a state where where a subsequent lzma_index_append() would allocate too little memory, and a buffer overflow would occur. This issue has been patched in version 5.8.3.
CVE-2026-39892 2 Cryptography.io, Pyca 2 Cryptography, Cryptography 2026-04-15 9.8 Critical
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.
