| CVE-2023-4039 | 1 Gnu | 1 Gcc | 2026-06-23 | 4.8 Medium |
| **DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself. | ||||
| CVE-2023-3576 | 3 Fedoraproject, Libtiff, Redhat | 3 Fedora, Libtiff, Enterprise Linux | 2026-06-23 | 5.5 Medium |
| A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes this memory leak issue, resulting an application crash, eventually leading to a denial of service. | ||||
| CVE-2025-2923 | 1 Hdfgroup | 1 Hdf5 | 2026-06-23 | 3.3 Low |
| A vulnerability, which was classified as problematic, has been found in HDF5 up to 1.14.6. Affected by this issue is the function H5F_addr_encode_len of the file src/H5Fint.c. The manipulation of the argument pp leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used. | ||||
| CVE-2026-12806 | 1 Edimax | 1 Br-6478ac V2 | 2026-06-23 | 8.8 High |
| A vulnerability has been found in Edimax BR-6478AC V2 1.23. The impacted element is the function formWlSiteSurvey of the file /goform/formWlSiteSurvey of the component POST Request Handler. The manipulation of the argument selSSID leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | ||||
| CVE-2026-12805 | 1 Offis | 1 Dcmtk | 2026-06-23 | 6.3 Medium |
| A flaw has been found in OFFIS DCMTK up to 3.7.0. The affected element is the function XMLNode::parseFile in the library ofstd/libsrc/ofxml.cc. Executing a manipulation can lead to heap-based buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. This patch is called 1d4b3815c0987840a983160bfc671fef63a3105b. It is best practice to apply a patch to resolve this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product. | ||||

| CVE-2025-39946 | 1 Linux | 1 Linux Kernel | 2026-06-18 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: tls: make sure to abort the stream if headers are bogus Normally we wait for the socket to buffer up the whole record before we service it. If the socket has a tiny buffer, however, we read out the data sooner, to prevent connection stalls. Make sure that we abort the connection when we find out late that the record is actually invalid. Retrying the parsing is fine in itself but since we copy some more data each time before we parse we can overflow the allocated skb space. Constructing a scenario in which we're under pressure without enough data in the socket to parse the length upfront is quite hard. syzbot figured out a way to do this by serving us the header in small OOB sends, and then filling in the recvbuf with a large normal send. Make sure that tls_rx_msg_size() aborts strp, if we reach an invalid record there's really no way to recover. | ||||
