nginx: NGINX: Arbitrary code execution or Denial of Service via heap-based buffer overflow with crafted HTTP/2 headers

A flaw was found in NGINX. When NGINX is configured to proxy HTTP/2 traffic using the ngxhttpproxyv2module or ngxhttpgrpcmodule with specific settings, a remote, unauthenticated attacker can send specially crafted large headers. This can trigger a heap-based buffer overflow, leading to a restart ...

CVE-2026-49414 ASLR bypass for setuid executables via procctl(2)

The ELF image activator cleared per-process ASLR preference flags for setuid binaries after the code that computes the PIE base address, rather than before. As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen. An unprivileged local user ca...

CVE-2026-49414

CVE-2026-49414 is a local ASLR bypass in FreeBSD: the ELF image activator clears per-process ASLR preferences for setuid binaries after computing the PIE base, allowing an unprivileged local user to disable ASLR for a setuid PIE binary via procctl(2) before execve(2). This makes exploitation of a...

BIT-NGINX-GATEWAY-2026-42530 NGINX Open-Source ngx_http_v3_module vulnerability

NGINX Open Source has a vulnerability in the ngxhttpv3module module. When NGINX Open Source is configured to use the HTTP/3 QUIC module, a remote unauthenticated attacker along with conditions beyond their control can use a specially crafted HTTP/3 session to reopen a QPACK encoder stream. This m...

CVE-2026-42055

CVE-2026-42055 affects NGINX Plus and NGINX Open Source via the ngx_http_proxy_v2_module and ngx_http_grpc_module. A remote, unauthenticated attacker can exploit scenarios where proxy_http_version 2 or grpc_pass is used, ignore_invalid_headers is off, and large_client_header_buffers is set to mul...

rsync: rsync: Remote memory disclosure via integer overflow in compressed-token decoding

A flaw was found in rsync. An authenticated daemon peer can exploit an integer overflow vulnerability in the compressed-token decoder. By carefully manipulating the compressed-token, a malicious sender can trigger an overflow, leading to remote memory disclosure. This allows an attacker to leak...
