Gentoo Linux Security Advisory

Title: TkMan: Insecure temporary file usage (GLSA 200909-07)
Severity: normal
Exploitable: local
Date: September 09, 2009
Bug(s): #247540
ID: 200909-07

Synopsis


An insecure temporary file usage has been reported in TkMan, allowing for
symlink attacks.


Background


TkMan is a graphical, hypertext manual page and Texinfo browser for
UNIX.


Affected Packages

Package: app-text/tkman
Vulnerable: < 2.2-r1
Unaffected: >= 2.2-r1
Architectures: All supported architectures


Description


Dmitry E. Oboukhov reported that TkMan does not handle the
"/tmp/tkman#####" and "/tmp/ll" temporary files securely.


Impact


A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.


Workaround


There is no known workaround at this time.


Resolution


All TkMan users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/tkman-2.2-r1"


References
