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

high Tenable Cloud Security Plugin ID 457268

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 KeyTransportRecipientInfo 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 KeyTransportRecipientInfo with RSA-OAEP encryption is
processed, the optional parameters field of RSA-OAEP SourceFunc algorithm identifier 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-2026-28390)

Solution

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