CVE-2026-44636 libsixel: integer overflow in encoder

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. From to 1.8.7-r1, signed integer overflow in sixelencodehighcolor's allocation size calculation can lead to a heap buffer overflow. The public sixelencode entry point validates only that width and height are greater th...

CVE-2026-42587

Netty CVE-2026-42587 affects HttpContentDecompressor and DelegatingDecompressorFrameListener. Before 4.2.13.Final and 4.1.133.Final, maxAllocation is enforced for gzip/deflate but ignored for br, zstd, or snappy, allowing an attacker to bypass the decompression limit via Content-Encoding: br and ...

CVE-2026-42587 Netty: HttpContentDecompressor maxAllocation bypass via Content-Encoding: br/zstd/snappy enables decompression bomb DoS

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate...

CVE-2026-44456 Hono: bodyLimit() can be bypassed for chunked / unknown-length requests

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.16, bodyLimit does not reliably enforce maxSize for requests without a usable Content-Length e.g. Transfer-Encoding: chunked. Oversized requests can reach handlers and return 200 instead of 413. Th...

CVE-2026-44456

CVE-2026-44456 affects hono; prior to version 4.12.16, bodyLimit() may fail to enforce maxSize for requests without Content-Length (e.g., Transfer-Encoding: chunked), allowing oversized requests to reach handlers and potentially return 200 instead of 413. The issue is resolved in 4.12.16. Affecte...

CVE-2026-8463

Crypt::Argon2 versions from 0.017 before 0.031 for Perl perform a heap out-of-bounds read in argon2verify on empty encoded input. The auto-detect form of argon2verify passes encodedlen - 1 as the length argument to memchr without checking that encodedlen is non-zero. When the encoded string is...

freerdp: FreeRDP: Denial of service due to use-after-free vulnerability

A flaw was found in FreeRDP. A remote attacker could exploit a use-after-free vulnerability in the xfSetWindowMinMaxInfo function. This occurs when a freed window pointer is dereferenced because the main thread concurrently deletes a window while the Remote Desktop Protocol RAIL channel thread is...

freerdp: FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId

A heap based buffer overflow flaw has been discovered in FreeRDP. This client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server can send a CACHEBITMAPORDER Rev1 with cacheId equal to maxCells,...

freerdp: FreeRDP: Denial of Service via endless blocking loop in Stream_EnsureCapacity

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The StreamEnsureCapacity function can create an endless blocking loop, leading to a Denial of Service DoS. This vulnerability can be exploited on 32-bit systems where the available physical memory is greater than o...
