Category:	Slackware Local Security Checks
Title:	Slackware: Security Advisory (SSA:2025-040-01)
Summary:	The remote host is missing an update for the 'openssl' package(s) announced via the SSA:2025-040-01 advisory.
Description:	Summary: The remote host is missing an update for the 'openssl' package(s) announced via the SSA:2025-040-01 advisory. Vulnerability Insight: 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! For more information, see: [link moved to references] (* Security fix *) patches/packages/openssl-solibs-1.1.1zb_p2-i586-1_slack15.0.txz: Upgraded. +--------------------------+ Affected Software/OS: 'openssl' package(s) on Slackware 15.0, Slackware current. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
