Ubuntu Security Notice 563-1 - 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.

Wei Wang discovered that an buffer overflow in the SNMP backend may lead to the execution of arbitrary code. Elias Pipping discovered that insecure handling of a temporary file in the pdftops.pl script may lead to local denial of service. This vulnerability is not exploitable in the default configuration.

Elias Pipping (Gentoo) discovered that the alternate pdftops filter creates temporary files with predictable file names when reading from standard input (CVE-2007-6358). Furthermore, the resolution of a Denial of Service vulnerability covered in GLSA 200703-28 introduced another Denial of Service vulnerability within SSL handling (CVE-2007-4045). Versions less than 1.3.5 are affected.
