Gentoo Linux Security Advisory

Title: ELinks: Arbitrary Samba command execution (GLSA 200701-27)
Severity: normal
Exploitable: remote
Date: January 30, 2007
Bug(s): #155358
ID: 200701-27

Synopsis


ELinks does not properly validate "smb://" URLs, making it vulnerable to
the execution of arbitrary Samba commands.


Background


ELinks is a text mode web browser.


Affected Packages

Package: www-client/elinks
Vulnerable: < 0.11.2
Unaffected: >= 0.11.2
Architectures: All supported architectures


Description


Teemu Salmela discovered an error in the validation code of "smb://"
URLs used by ELinks, the same issue as reported in GLSA 200612-16
concerning Links.


Impact


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 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.


Workaround


There is no known workaround at this time.


Resolution


All ELinks users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/elinks-0.11.2"


References

CVE-2006-5925
