Echo: openssl-3.5.0: security update to 3.5.0+e1

low Tenable Self-Hosted Container Security Plugin ID 478560

Description

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

 - Issue summary: A non-constant-time optimized implementation of scalar point multiplication is used for SM2
 private key operations on ARM64 and RISC-V platforms. Impact summary: An attacker able to measure the time
 taken by, or to observe the cache-line access pattern of SM2 signing or decryption on an affected platform
 can learn information about the secret scalar. CWE: CWE-208: Observable Timing Discrepancy Description: On
 ARM64 and RISC-V processors, the SM2 curve uses an optimized scalar multiplication implementation whose
 conditional branches and table look ups are chosen according to the bits of the secret scalar. The
 execution time and the cache-access pattern therefore depend on the long-term private key (during SM2
 decryption) or the per-signature nonce (during SM2 signature generation), forming a timing and cache side-
 channel. FIPS Impact: no SM2 is not a FIPS algorithm and the optimized SM2 implementation is not part of
 the FIPS module. OpenSSL 4.0, 3.6, 3.5 and 3.4 are vulnerable to this issue on AArch64 and RISC-V. OpenSSL
 3.0, 1.1.1 and 1.0.2 are not affected by this issue. OpenSSL 4.0 users should upgrade to OpenSSL 4.0.3.
 OpenSSL 3.6 users should upgrade to OpenSSL 3.6.5. OpenSSL 3.5 users should upgrade to OpenSSL 3.5.9.
 OpenSSL 3.4 users should upgrade to OpenSSL 3.4.8. This issue was reported on 2 May 2026 by Abhinav
 Agarwal. It was independently reported on 6 June 2026 by Feng Xue. The fix was developed by Igor Ustinov.
