"Teemu Salmela discovered that Elinks did not properly validate input
when processing smb:// URLs. If a user were tricked into viewing a
malicious website and had smbclient installed, a remote attacker could
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2006-5925)

Jakub Wilk discovered a logic error in Elinks, leading to a buffer
overflow. If a user were tricked into viewing a malicious website, a
remote attacker could cause a denial of service via application crash,
or possibly execute arbitrary code with the privileges of the user
invoking the program. (CVE-2008-7224).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
