Gentoo Linux Security Advisory

Title: Net-SNMP: fixproc insecure temporary file creation (GLSA 200505-18)
Severity: normal
Exploitable: local
Date: May 23, 2005
Updated: May 22, 2006
Bug(s): #91792
ID: 200505-18

Synopsis

Net-SNMP creates temporary files in an insecure manner, possibly allowing the execution of arbitrary code.

Background

Net-SNMP is a suite of applications used to implement the Simple Network Management Protocol.

Affected Packages

Package: net-analyzer/net-snmp
Vulnerable: < 5.2.1-r1
Unaffected: >= 5.2.1-r1
Architectures: All supported architectures


Description

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.

Resolution

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


References

CVE-2005-1740
