Echo: openssl: security update to 3.5.7-1~deb13u2

medium Tenable Self-Hosted Container Security Plugin ID 458156

Description

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

- Issue summary: The OpenSSL Certificate Management Protocol (CMP) caches additional certificates
(extraCerts) sent in a CMP message, but never expunges them (for instance if they are invalid). If a
server reuses an OSSL_CMP_CTX frequently, this cache of extraCerts may grow unboundedly, and a malicious
client may flood a CMP server with requests driving this growth. Impact summary: Users utilizing a CMP
server that reuses a single OSSL_CMP_CTX for the lifetime of a server process may observe unbounded memory
growth in the event a malicious client repeatedly sends requests containing unique extra certificates,
which may lead to OOM conditions. CWE: CWE-770: Allocation of Resources Without Limits or Throttling
Description: If a remote user sends CMP messages to a server with a list of extraCerts and the message is
rejected, the extraCerts from the message remains in the server contexts untrusted certificate stack. This
exposes servers with long lived ctx objects to Denial of Service attacks in which an attacker sends
messages intending to be rejected with a large list of additional certificates repeatedly, forcing the
server to store them indefinitely. The issue was fixed by removing the added extra certs if the message is
rejected, using the same method as when the context is configured to not do caching at all. FIPS impact:
no As the CMP code lives outside the FIPS module boundary, no FIPS modules are affected by this CVE.
(CVE-2026-63074)

Solution
