Echo: openssl: security update to 3.5.5-1~deb13u2

high Tenable Cloud Security Plugin ID 461333

Description

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

 - Issue summary: During processing of a crafted CMS EnvelopedData message with KeyAgreeRecipientInfo a NULL
 pointer dereference can happen. Impact summary: Applications that process attacker-controlled CMS data may
 crash before authentication or cryptographic operations occur resulting in Denial of Service. When a CMS
 EnvelopedData message that uses KeyAgreeRecipientInfo is processed, the optional parameters field of
 KeyEncryptionAlgorithmIdentifier is examined without checking for its presence. This results in a NULL
 pointer dereference if the field is missing. Applications and services that call CMS_decrypt() on
 untrusted input (e.g., S/MIME processing or CMS-based protocols) are vulnerable. The FIPS modules in 3.6,
 3.5, 3.4, 3.3 and 3.0 are not affected by this issue, as the affected code is outside the OpenSSL FIPS
 module boundary. (CVE-2026-28389)

Solution

Update the openssl library and its related packages to version 3.5.5-1~deb13u2 or later.
