Echo: openssl: security update to 3.5.4-1~deb13u2

medium Tenable Cloud Security Plugin ID 465407

Description

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

 - Issue summary: An invalid or NULL pointer dereference can happen in an application processing a malformed
 PKCS#12 file. Impact summary: An application processing a malformed PKCS#12 file can be caused to
 dereference an invalid or NULL pointer on memory read, resulting in a Denial of Service. A type confusion
 vulnerability exists in PKCS#12 parsing code where an ASN1_TYPE union member is accessed without first
 validating the type, causing an invalid pointer read. The location is constrained to a 1-byte address
 space, meaning any attempted pointer manipulation can only target addresses between 0x00 and 0xFF. This
 range corresponds to the zero page, which is unmapped on most modern operating systems and will reliably
 result in a crash, leading only to a Denial of Service. Exploiting this issue also requires a user or
 application to process a maliciously crafted PKCS#12 file. It is uncommon to accept untrusted PKCS#12
 files in applications as they are usually used to store private keys which are trusted by definition. For
 these reasons, the issue was assessed as Low severity. The FIPS modules in 3.5, 3.4, 3.3 and 3.0 are not
 affected by this issue, as the PKCS12 implementation is outside the OpenSSL FIPS module boundary. OpenSSL
 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this issue. OpenSSL 1.0.2 is not affected by this
 issue. (CVE-2026-22795)

Solution

Update the openssl library and its related packages to version 3.5.4-1~deb13u2 or later.
