EUVD-2026-64846

RustDesk's Windows clipboard redirection copies a peer-supplied length into a fixed-size caller buffer without an upper bound check. When an OLE paste consumer such as explorer.exe calls IStream::Read with a buffer of cb bytes, CliprdrStreamRead in libs/clipboard/src/windows/wfcliprdr.c requests...

CVE-2026-76840

RustDesk (through 1.4.9 ) contains a heap buffer overflow in its Windows CLIPRDR clipboard redirection module (libs/clipboard/src/windows/wf_cliprdr.c). The peer-supplied cbRequested length from a CLIPRDR FileContentsResponse is copied via CopyMemory into the caller's fixed-size buffer without be...

CVE-2026-72854

A flaw was found in msgpack-c. An integer overflow vulnerability exists in the msgpackunpackerexpandbuffer function. This flaw can lead to an undersized memory buffer being allocated, even though the system reports a successful reservation. If an attacker can influence the length provided to the...

sqlite: SQLite: Arbitrary code execution via crafted FTS5 full-text search data

A flaw was found in SQLite's FTS5 full-text search extension. This vulnerability involves memory corruption, specifically an out-of-bounds read and a heap buffer overflow, which can be triggered by supplying a crafted database with malformed FTS5 page data. When an FTS5 MATCH query is executed...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: fix OOB read in decodechoice In decodechoice, the boundary check before getlen uses the variable len, which remains 0 after initialization at the beginning of the function: unsigned int type, ext, len ...

Astra Linux – Vulnerability in libxml-parser-perl

XML::Parser versions up to 2.47 for Perl have a heap buffer overflow issue in stserialstack. In the case where stackptr == stacksize - 1, the stack will NOT be expanded. As a result, the new value will be written at location ++stackptr, which equals stacksize. This means that the new value falls...

Astra Linux – Vulnerability in Freetype
