Bug#655044: glib2.0: ghashtable vulnerable to oCert-2011-003 DOS attacks

[John Lightsey]

Source: glib2.0
Severity: important
Tags: security

The standard hashing functions provided with the ghashtable implementation
in glib are vulnerable to the algorithmic complexity attacks described in
oCert-2011-003

http://www.ocert.org/advisories/ocert-2011-003.html

This was reported upstream in 2003 when Perl fixed their hashing
implementation by introducing a random hash seed. The upstream discussion
is archived here:
