Title:	Slackware: Security Advisory (SSA:2024-031-01)
Summary:	The remote host is missing an update for the 'sendmail' package(s) announced via the SSA:2024-031-01 advisory.
Description:	Summary: The remote host is missing an update for the 'sendmail' package(s) announced via the SSA:2024-031-01 advisory. Vulnerability Insight: New sendmail packages are available for Slackware 15.0 and -current to fix a security issue. Here are the details from the Slackware 15.0 ChangeLog: +--------------------------+ extra/sendmail/sendmail-8.18.1-i586-1_slack15.0.txz: Upgraded. sendmail through 8.17.2 allows SMTP smuggling in certain configurations. Remote attackers can use a published exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, allowing bypass of an SPF protection mechanism. This occurs because sendmail supports . but some other popular e-mail servers do not. This is resolved in 8.18 and later versions with 'o' in srv_features. For more information, see: [link moved to references] (* Security fix *) extra/sendmail/sendmail-cf-8.18.1-noarch-1_slack15.0.txz: Upgraded. +--------------------------+ Affected Software/OS: 'sendmail' 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:N/I:P/A:N
