CVE-2026-57881 1 Geovision Inc. 1 Gv-lpclpc2011 2211 2026-06-26 9.8 Critical
An unauthenticated stack-based buffer overflow vulnerability exists in vlsvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient length validation when processing remote login data. A remote attacker may exploit this vulnerability by sending crafted login data with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.
CVE-2026-57878 1 Geovision Inc. 1 Gv-lpclpc2011 2211 2026-06-26 9.8 Critical
An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by sending a crafted HTTP request with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.
CVE-2026-56766 1 Vanhauser-thc 1 Thc-hydra 2026-06-26 8.8 High
Hydra through 9.7, fixed in commit 9cc84c2, contains a stack buffer overflow in NTLM authentication across SMTP, POP3, IMAP, NNTP, HTTP, HTTP-Proxy, and HTTP-Proxy-Urlenum modules when processing malicious NTLM Type-2 challenges. A malicious server can send a crafted NTLM Type-2 challenge with an excessively long domain string, causing base64-encoded response data to overflow a 500-byte stack buffer by 18 to 330 bytes, enabling remote code execution on systems without stack protection.
CVE-2025-60474 1 Gpac 1 Mp4box 2026-06-25 7.5 High
A buffer overflow in the gf_media_import function (/media_tools/av_parsers.c) of GPAC Project/MP4Box before 26.02.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted input.
CVE-2026-50259 3 Redhat, X.org, Xorg 5 Enterprise Linux, X Server, Xorg-server and 2 more 2026-06-25 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. _XkbSetMapChecks() declares a fixed-size stack buffer mapWidths[256] indexed by key type index. The helper function CheckKeyTypes() writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50258 2 Redhat, X.org 3 Enterprise Linux, X Server, Xwayland 2026-06-25 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups but CheckKeyTypes() does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift levels and trigger stack overflows. This is caused by an incomplete fix of CVE-2025-26597. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2026-50256 2 Redhat, X.org 4 Enterprise Linux, X Server, Xorg-server and 1 more 2026-06-25 7.8 High
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias target name length is 1024 bytes. A font alias name between 257 and 1023 bytes causes the X server to copy that name into the undersized stack buffer without further checks. This may be used to crash the server, or for privilege escalation if the X server runs as root.
CVE-2025-6170 2 Redhat, Xmlsoft 7 Enterprise Linux, Hummingbird, Jboss Core Services and 4 more 2026-06-25 2.5 Low
A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
CVE-2025-9820 1 Redhat 9 Ceph Storage, Discovery, Enterprise Linux and 6 more 2026-06-25 4 Medium
A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.
CVE-2025-6021 2 Redhat, Xmlsoft 31 Discovery, Enterprise Linux, Enterprise Linux Eus and 28 more 2026-06-25 7.5 High
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2025-5278 1 Redhat 3 Enterprise Linux, Openshift, Rhivos 2026-06-25 4.4 Medium
A flaw was found in GNU Coreutils. The sort utility's begfield() function is vulnerable to a heap buffer under-read. The program may access memory outside the allocated buffer if a user runs a crafted command using the traditional key format. A malicious input could lead to a crash or leak sensitive data.
CVE-2025-46398 2 Fig2dev Project, Redhat 3 Fig2dev, Enterprise Linux, Rhivos 2026-06-25 5.5 Medium
In xfig diagramming tool, a stack-overflow while running fig2dev allows memory corruption via local input manipulation via read_objects function.
CVE-2025-46397 2 Fig2dev Project, Redhat 4 Fig2dev, Enterprise Linux, Rhel Eus and 1 more 2026-06-25 7.8 High
A flaw was found in xfig. This vulnerability allows possible code execution via local input manipulation via bezier_spline function.
CVE-2025-12464 1 Redhat 3 Enterprise Linux, Openshift, Rhivos 2026-06-25 6.2 Medium
A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.
CVE-2025-48796 1 Redhat 2 Enterprise Linux, Rhivos 2026-06-25 7.3 High
A flaw was found in GIMP. The GIMP ani_load_image() function is vulnerable to a stack-based overflow. If a user opens.ANI files, GIMP may be used to store more information than the capacity allows. This flaw allows a malicious ANI file to trigger arbitrary code execution.
CVE-2025-26595 3 Redhat, Tigervnc, X.org 10 Enterprise Linux, Rhel Aus, Rhel E4s and 7 more 2026-06-25 7.8 High
A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size.
CVE-2026-51844 1 Tenda 1 Ac7 2026-06-24 9.8 Critical
Tenda AC7 v15.03.06.44 contains a stack buffer overflow vulnerability in the /goform/AdvSetMacMtuWan interface via the cloneType parameter.
CVE-2026-12485 1 Geovision Inc. 2 Gv-i/o Box 4e, Gv-i O Box 4e 2026-06-24 10 Critical
GV-I/O Box 4E is a smart embedded device with 4 input and 4 relays output that can be controlled over Ethernet and RS-485. DVRSearch is a service running by default on the IOBox listening for UDP messages on port 10001. Any user on the network can send messages to this service and interact with it. Upon receiving a UDP message, the server reads at most 1460 bytes into a local buffer and a pointer to the buffer is stored in a global variable: #### IP field stack overflow The following code is vulnerable to a stack overflow that is attacker-controlled: v3 = strlen(g_network_config->ip_addr); memcpy(&reply_buf[36], g_network_config->ip_addr, v3);
CVE-2026-12847 1 Geovision Inc. 1 Gv-i O Box 4e 2026-06-24 10 Critical
