Description Philipp Hahn

New Debian net-snmp 5.7.2.1+dfsg-1+deb8u1+b1 fixes:
This update addresses the following issues:
* The snmp_pdu_parse function in net-snmp does not remove the varBind
  variable in a netsnmp_variable_list item when parsing of the SNMP PDU
  fails, which allows remote attackers to cause a denial of service (crash)
  and possibly execute arbitrary code via a crafted packet. (CVE-2015-5621)
* NET-SNMP contains a heap corruption vulnerability in the UDP protocol
  handler that can result in command execution. (CVE-2018-1000116)

CVE-2015-5621 net-snmp: snmp_pdu_parse() incompletely parsed varBinds left in list of variables
CVE-2018-1000116 net-snmp: Heap corruption in snmp_pdu_parse function in snmplib/snmp_api.c

[4.2-3] f04a8b3983 Bug #46770: net-snmp_5.7.2.1+dfsg-1+deb8u1+b1

Annoucne will fail as this is a BINNMU in Debian:
 [FAIL] changes.valid: Mismatching binary package version: 5.7.2.1+dfsg-1+deb8u1+b1 != tkmib 5.7.2.1+dfsg-1+deb8u1 from net-snmp 5.7.2.1+dfsg-1+deb8u1

* No UCS specific patches
* Comparison to previously shipped version ok
* Binary package update Ok
* Advisory Ok

(In reply to Philipp Hahn from comment #2)

> 5.7.2.1+dfsg-1+deb8u1

This was an error in the YAML file: I specified the binary package version containing the additional '+b1' binNMU suffix instead of the source package version.
