GLSA-200505-18 : Net-SNMP: fixproc insecure temporary file creation

critical Nessus Plugin ID 18382

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200505-18 (Net-SNMP: fixproc insecure temporary file creation)

 The fixproc application of Net-SNMP creates temporary files with predictable filenames.
 Impact :

 A malicious local attacker could exploit a race condition to change the content of the temporary files before they are executed by fixproc, possibly leading to the execution of arbitrary code. A local attacker could also create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When fixproc is executed, this would result in the file being overwritten.
 Workaround :

 There is no known workaround at this time.

Solution

All Net-SNMP users should upgrade to the latest available version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-analyzer/net-snmp-5.2.1-r1'
