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

medium Tenable Self-Hosted Container Security Plugin ID 461151

Description

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

 - Issue summary: When using the low-level OCB API directly with AES-NI or<br>other hardware-accelerated code
 paths, inputs whose length is not a multiple<br>of 16 bytes can leave the final partial block unencrypted
 and unauthenticated.<br><br>Impact summary: The trailing 1-15 bytes of a message may be exposed
 in<br>cleartext on encryption and are not covered by the authentication tag,<br>allowing an attacker to
 read or tamper with those bytes without detection.<br><br>The low-level OCB encrypt and decrypt routines
 in the hardware-accelerated<br>stream path process full 16-byte blocks but do not advance the
 input/output<br>pointers. The subsequent tail-handling code then operates on the original<br>base
 pointers, effectively reprocessing the beginning of the buffer while<br>leaving the actual trailing bytes
 unprocessed. The authentication checksum<br>also excludes the true tail bytes.<br><br>However, typical
 OpenSSL consumers using EVP are not affected because the<br>higher-level EVP and provider OCB
 implementations split inputs so that full<br>blocks and trailing partial blocks are processed in separate
 calls, avoiding<br>the problematic code path. Additionally, TLS does not use OCB ciphersuites.<br>The
 vulnerability only affects applications that call the low-level<br>CRYPTO_ocb128_encrypt() or
 CRYPTO_ocb128_decrypt() functions directly with<br>non-block-aligned lengths in a single call on hardware-
 accelerated builds.<br>For these reasons the issue was assessed as Low severity.<br><br>The FIPS modules
 in 3.6, 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected<br>by this issue, as OCB mode is not a FIPS-
 approved algorithm.<br><br>OpenSSL 3.6, 3.5, 3.4, 3.3, 3.0 and 1.1.1 are vulnerable to this
 issue.<br><br>OpenSSL 1.0.2 is not affected by this issue. (CVE-2025-69418)

Solution

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