Category:	Slackware Local Security Checks
Title:	Slackware: Security Advisory (SSA:2020-140-01)
Summary:	The remote host is missing an update for the 'bind' package(s) announced via the SSA:2020-140-01 advisory.
Description:	Summary: The remote host is missing an update for the 'bind' package(s) announced via the SSA:2020-140-01 advisory. Vulnerability Insight: New bind packages are available for Slackware 14.0, 14.1, 14.2, and -current to fix security issues. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/bind-9.11.19-i586-1_slack14.2.txz: Upgraded. This update fixes security issues: A malicious actor who intentionally exploits the lack of effective limitation on the number of fetches performed when processing referrals can, through the use of specially crafted referrals, cause a recursing server to issue a very large number of fetches in an attempt to process the referral. This has at least two potential effects: The performance of the recursing server can potentially be degraded by the additional work required to perform these fetches, and the attacker can exploit this behavior to use the recursing server as a reflector in a reflection attack with a high amplification factor. Replaying a TSIG BADTIME response as a request could trigger an assertion failure. For more information, see: [links moved to references] (* Security fix *) +--------------------------+ Affected Software/OS: 'bind' package(s) on Slackware 14.0, Slackware 14.1, Slackware 14.2, Slackware current. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
