GLSA-200612-16 : Links: Arbitrary Samba command execution
High Nessus Plugin ID 23873
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200612-16 (Links: Arbitrary Samba command execution)
Teemu Salmela discovered that Links does not properly validate 'smb://' URLs when it runs smbclient commands.
A remote attacker could entice a user to browse to a specially crafted 'smb://' URL and execute arbitrary Samba commands, which would allow the overwriting of arbitrary local files or the upload or the download of arbitrary files. This vulnerability can be exploited only if 'smbclient' is installed on the victim's computer, which is provided by the 'samba' Gentoo package.
There is no known workaround at this time.
SolutionAll Links users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-client/links-2.1_pre26'
