Echo: nginx: security update to 1.26.3-3+deb13u10

critical Tenable Self-Hosted Container Security Plugin ID 476952

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_core_module module. When
asynchronous file I/O (AIO) is enabled in certain configurations, processing a Server Side Includes (SSI)
page containing “include virtual” commands may trigger a Use-After-Free (UAF) in the NGINX worker process.
This may cause memory corruption or a worker process crash. Additionally, attackers can execute code on
systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR.
Impact: This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX
system, corrupt its memory, or possibly trigger code execution. There is no control plane exposure; this
is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are
not evaluated. (CVE-2026-97205)

Solution

Update the nginx library and its related packages to version 1.26.3-3+deb13u10 or later.
