| Description: | Summary:
The remote host is missing an update for the 'firefox' package(s) announced via the USN-351-1 advisory.
Vulnerability Insight:
Various flaws have been reported that allow an attacker to execute
arbitrary code with user privileges by tricking the user into opening
a malicious web page containing JavaScript. (CVE-2006-4253,
CVE-2006-4565, CVE-2006-4566, CVE-2006-4568, CVE-2006-4569
CVE-2006-4571)
The NSS library did not sufficiently check the padding of PKCS #1 v1.5
signatures if the exponent of the public key is 3 (which is widely
used for CAs). This could be exploited to forge valid signatures
without the need of the secret key. (CVE-2006-4340)
Jon Oberheide reported a way how a remote attacker could trick users
into downloading arbitrary extensions with circumventing the normal
SSL certificate check. The attacker would have to be in a position to
spoof the victim's DNS, causing them to connect to sites of the
attacker's choosing rather than the sites intended by the victim. If
they gained that control and the victim accepted the attacker's cert
for the Mozilla update site, then the next update check could be
hijacked and redirected to the attacker's site without
detection. (CVE-2006-4567)
Affected Software/OS:
'firefox' package(s) on Ubuntu 6.06.
