Scientific Linux Security Update : gnutls on SL7.x x86_64 (20170801)
High Nessus Plugin ID 102642
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThe following packages have been upgraded to a later upstream version:
Security Fix(es) :
- A double-free flaw was found in the way GnuTLS parsed certain X.509 certificates with Proxy Certificate Information extension. An attacker could create a specially crafted certificate which, when processed by an application compiled against GnuTLS, could cause that application to crash. (CVE-2017-5334)
- Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash. (CVE-2017-5335, CVE-2017-5336, CVE-2017-5337, CVE-2017-7869)
- A NULL pointer dereference flaw was found in the way GnuTLS processed ClientHello messages with status_request extension. A remote attacker could use this flaw to cause an application compiled with GnuTLS to crash. (CVE-2017-7507)
- A flaw was found in the way GnuTLS validated certificates using OCSP responses. This could falsely report a certificate as valid under certain circumstances. (CVE-2016-7444)
SolutionUpdate the affected packages.
