xorg-x11-server: xorg-x11-server-Xwayland: xorg-x11-server: stack buffer overflow in XKB SetMap request via mapWidths indexing
A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...

The Avro array and map decoders loop over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 and arm64 targets. A producer can declare a block of up to...
nginx 1.15.8 < 1.30.4 / 1.31.2 < 1.31.3 Memory Disclosure
According to its Server response header, the installed version of nginx is 1.30.0 prior to 1.30.4, or 1.31.2 prior to 1.31.3. It is, therefore, affected by memory disclosure vulnerability: - NGINX Plus and NGINX Open Source have a vulnerability in the ngxhttpslicemodule module. When the slice...

The Avro map decoder accepts attacker-controlled block-element counts from the wire format and grows the destination map without enforcing an upper bound. A producer can declare an arbitrarily large map in one block, or chunked across many sub-limit blocks and exhaust process memory until the OOM...

PT-2026-65347
Several Avro decoder paths read attacker-controlled 64-bit values from the wire format and either narrowed them to platform-sized int before bounds-checking, or summed them with overflow-prone signed-int arithmetic. On 32-bit targets, the truncation paths can silently bypass byte-slice limits,...

nginx: NGINX: Arbitrary code execution via crafted HTTP requests
A flaw was found in NGINX. An unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP requests when the map directive uses regular expression regex matching and references regex capture variables before referencing the map output variable. This can lead to a heap...
