Details

Wei Wang discovered that the SNMP discovery backend did not
correctly calculate the length of strings. If a user were tricked into
scanning for printers, a remote attacker could send a specially crafted
packet and possibly execute arbitrary code.

Elias Pipping discovered that temporary files were not handled safely
in certain situations when converting PDF to PS. A local attacker could
cause a denial of service.

Ubuntu 7.10
