Category:	Slackware Local Security Checks
Title:	Slackware: Security Advisory (SSA:2019-086-01)
Summary:	The remote host is missing an update for the 'gnutls' package(s) announced via the SSA:2019-086-01 advisory.
Description:	Summary: The remote host is missing an update for the 'gnutls' package(s) announced via the SSA:2019-086-01 advisory. Vulnerability Insight: New gnutls packages are available for Slackware 14.2 and -current to fix security issues. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/gnutls-3.6.7-i586-1_slack14.2.txz: Upgraded. Fixes security issues: libgnutls, gnutls tools: Every gnutls_free() will automatically set the free'd pointer to NULL. This prevents possible use-after-free and double free issues. Use-after-free will be turned into NULL dereference. The counter-measure does not extend to applications using gnutls_free(). libgnutls: Fixed a memory corruption (double free) vulnerability in the certificate verification API. Reported by Tavis Ormandy, addressed with the change above. [GNUTLS-SA-2019-03-27, #694] libgnutls: Fixed an invalid pointer access via malformed TLS1.3 async messages, Found using tlsfuzzer. [GNUTLS-SA-2019-03-27, #704] libgnutls: enforce key usage limitations on certificates more actively. Previously we would enforce it for TLS1.2 protocol, now we enforce it even when TLS1.3 is negotiated, or on client certificates as well. When an inappropriate for TLS1.3 certificate is seen on the credentials structure GnuTLS will disable TLS1.3 support for that session (#690). libgnutls: enforce the equality of the two signature parameters fields in a certificate. We were already enforcing the signature algorithm, but there was a bug in parameter checking code. (* Security fix *) +--------------------------+ Affected Software/OS: 'gnutls' package(s) on 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:P/I:N/A:N
