CVE-2026-51843 1 Tenda 1 Ac7 2026-06-22 9.8 Critical
Tenda AC7 v15.03.06.44 contains a stack buffer overflow vulnerability in the /goform/AdvSetMacMtuWan interface via the wanMTU parameter.
CVE-2026-48715 1 Radvd-project 1 Radvdump 2026-06-22 N/A
radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the `radvdump` utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, `print_ff()` copies up to 2032 bytes from attacker-controlled packet data into a 16-byte `struct in6_addr` on the stack, overflowing by up to 2016 bytes. Note that the main `radvd` daemon is not affected by the vulnerability. Version 2.21 patches the issue.
CVE-2025-55660 1 Gpac 1 Mp4box 2026-06-19 5.5 Medium
A stack overflow in the gf_opus_read_length function (media_tools/av_parsers.c) of GPAC MP4Box v2.4 allows attackers to cause a Denial of Service (DoS) via supplying a crafted MP4 file.
CVE-2026-7273 1 Zyxel 10 Gs1900-10hp Firmware, Gs1900-16 Firmware, Gs1900-24 Firmware and 7 more 2026-06-18 8.8 High
A stack-based buffer overflow vulnerability in the CGI program of Zyxel GS1900-48HPv2 firmware versions through 2.90(ABTQ.1)C0 could allow a LAN-based, unauthenticated attacker to exploit the flaw and potentially execute OS commands via a crafted HTTP request.
CVE-2026-55738 1 Rxi 1 Microtar 2026-06-17 8.8 High
A stack-based buffer overflow exists in the raw_to_header() function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy() without guaranteeing null termination of the source. The POSIX ustar format permits these fixed-width fields to be fully populated with non-null bytes, so a crafted archive whose linkname field (followed by the trailing padding of the 512-byte raw header) contains no null terminator causes strcpy() to read past the end of the 512-byte raw header stack buffer and to write past the destination header buffer. A remote attacker who supplies a crafted TAR archive that the victim opens or parses (via mtar_open(), mtar_read_header(), or mtar_find()) can cause an out-of-bounds read and a stack buffer overflow, resulting in denial of service (crash) and potentially arbitrary code execution. Confirmed with AddressSanitizer: stack-buffer-overflow READ of size 356 in raw_to_header at src/microtar.c:112.
CVE-2026-26241 2 Qnap, Qnap Systems 2 File Station, File Station 5 2026-06-17 9.1 Critical
A buffer overflow vulnerability has been reported to affect File Station 5. The remote attackers can then exploit the vulnerability to modify memory or crash processes. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5243 and later
CVE-2026-26239 2 Qnap, Qnap Systems 2 File Station, File Station 5 2026-06-17 8.1 High
A buffer overflow vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to modify memory or crash processes. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5208 and later
CVE-2026-26240 2 Qnap, Qnap Systems 2 File Station, File Station 5 2026-06-17 9.1 Critical
A buffer overflow vulnerability has been reported to affect File Station 5. The remote attackers can then exploit the vulnerability to modify memory or crash processes. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5243 and later
CVE-2026-8356 1 The Document Foundation 1 Libreoffice 2026-06-16 5.5 Medium
LibreOffice can import presentations in the legacy binary PPT format. A stack buffer overflow existed when importing a colour-replacement record. Two fixed-size colour tables were filled from the file, but the write position was not reset between the two passes over the record, so a file whose combined colour counts exceeded the table size wrote past the end of the tables on the stack. In fixed versions the unused second pass is no longer read into those tables.
CVE-2026-10829 1 Moxa 2 Nport W2150a-w4 W2250a-w4 Series, Nport W2150a W2250a Series 2026-06-16 N/A
A stack-based buffer overflow vulnerability has been found in the NPort W2150A-W4/W2250A-W4 Series version 1.5 and earlier. This vulnerability stems from insufficient input validation of user-supplied input in the "Server location" parameter on the Basic settings page. An attacker could exploit this vulnerability by sending crafted input to the web service, resulting in memory corruption. Successful exploitation of this vulnerability could allow remote code execution on the target system with root privileges.
CVE-2026-12200 1 Ritlabs 1 Tinyweb Server 2026-06-15 7.3 High
A security vulnerability has been detected in Ritlabs TinyWeb Server up to 1.94 on Win32. This impacts an unknown function in the library libeay32.dll.html of the component Header Handler. The manipulation of the argument Authorization leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-11793 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2026-06-15 4.9 Medium
A stack buffer overflow flaw was found in 389 Directory Server. The checkPrefix() function in pw.c copies an attacker-controlled algorithm ID into a 256-byte stack buffer without bounds checking when parsing reversible-encrypted attribute values. An attacker with Directory Manager privileges can crash the LDAP server by storing a crafted credential with an oversized algorithm ID. FORTIFY_SOURCE mitigates this to denial of service only.
CVE-2025-66280 2 Qnap, Qnap Systems 4 Qts, Quts Hero, Qts and 1 more 2026-06-15 7.2 High
An integer overflow or wraparound vulnerability has been reported to affect several QNAP operating system versions. If a remote attacker gains an administrator account, they can then exploit the vulnerability to compromise the security of the system. We have already fixed the vulnerability in the following versions: QTS 5.2.9.3410 build 20260214 and later QuTS hero h5.2.9.3410 build 20260214 and later QuTS hero h5.3.4.3500 build 20260520 and later QuTS hero h6.0.0.3397 build 20260206 and later
