*** This bug is a security vulnerability *** Public security bug reported:
CVE-2008-0960 description: "Some SNMP implementations include incomplete HMAC authentication code that allows spoofing of authenticated SNMPv3 packets. The authentication code reads the length to be checked from sender input, this allows the sender to supply single byte HMAC code and have a 1 in 256 chance of matching the correct HMAC and authenticating, as only the first byte will be checked. The sender would need to know a valid username. Currently Net-SNMP and UCD-SNMP are known to be vulnerable, other SNMP implementations may also be affected. The eCos project includes code derived from UCD-SNMP and is therefore also affected." http://www.ocert.org/advisories/ocert-2008-006.html See also: http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-0960 http://www.kb.cert.org/vuls/id/878044 ** Affects: ecos (Ubuntu) Importance: Undecided Status: New ** Affects: net-snmp (Ubuntu) Importance: Undecided Status: New ** Affects: ucd-snmp (Ubuntu) Importance: Undecided Status: New ** Visibility changed to: Public ** CVE added: http://www.cve.mitre.org/cgi- bin/cvename.cgi?name=2008-0960 ** Also affects: ecos (Ubuntu) Importance: Undecided Status: New -- [CVE-2008-0960] Multiple SNMP implementations HMAC authentication spoofing https://bugs.launchpad.net/bugs/239129 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
