CentOS Errata and Security Advisory CESA-2005:395
SNMP (Simple Network Management Protocol) is a protocol used for network management.
A denial of service bug was found in the way net-snmp uses network stream protocols. It is possible for a remote attacker to send a net-snmp agent a specially crafted packet that will crash the agent. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2177 to this issue.
An insecure temporary file usage bug was found in net-snmp's fixproc command. It is possible for a local user to modify the content of temporary files used by fixproc that can lead to arbitrary command execution. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1740 to this issue.
Additionally, the following bugs have been fixed: - The lmSensors are correctly recognized, snmp deamon no longer segfaults - The larger swap partition sizes are correctly reported - Querying hrSWInstalledLastUpdateTime no longer crashes the snmp deamon - Fixed error building ASN.1 representation - The 64-bit network counters correctly wrap - Large file systems are correctly handled - Snmptrapd initscript correctly reads options from its configuration file /etc/snmp/snmptrapd.options - Snmp deamon no longer crashes when restarted using the agentX protocol - snmp daemon now reports gigabit Ethernet speeds correctly - MAC adresses are shown when requested instead of IP adresses
All users of net-snmp should upgrade to these updated packages, which resolve these issues.
