Slackware Security[slackware-security] openssl (SSA:2025-040-01)
New openssl packages are available for Slackware 15.0 and -current to
fix a security issue.
Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/openssl-1.1.1zb_p2-i586-1_slack15.0.txz: Upgraded.
Apply patch to fix a low severity security issue:
Fix timing side-channel in ECDSA signature computation.
There is a timing signal of around 300 nanoseconds when the top word of
the inverted ECDSA nonce value is zero. This can happen with significant
probability only for some of the supported elliptic curves. In particular
the NIST P-521 curve is affected. To be able to measure this leak, the
attacker process must either be located in the same physical computer or
must have a very fast network connection with low latency.
This CVE was fixed by the second 1.1.1zb release that is only available to
subscribers to OpenSSL's premium extended support. The patch was prepared
by backporting from the OpenSSL-3.0 repo.
Thanks to Ken Zalewski for the patch!
