-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [slackware-security] openssh (SSA:2025-049-01) New openssh packages are available for Slackware 15.0 and -current to fix security issues. Here are the details from the Slackware 15.0 ChangeLog: +--------------------------+ patches/packages/openssh-9.9p2-i586-1_slack15.0.txz: Upgraded. This release fixes two security bugs: ssh(1) in OpenSSH versions 6.8p1 to 9.9p1 (inclusive) contained a logic error that allowed an on-path attacker (a.k.a MITM) to impersonate any server when the VerifyHostKeyDNS option is enabled. This option is off by default. sshd(8) in OpenSSH versions 9.5p1 to 9.9p1 (inclusive) is vulnerable to a memory/CPU denial-of-service related to the handling of SSH2_MSG_PING packets. This condition may be mitigated using the existing PerSourcePenalties feature. Both vulnerabilities were discovered and demonstrated to be exploitable by the Qualys Security Advisory team. We thank them for their detailed review of OpenSSH.
