An insecure temporary file usage has been reported in TkMan, allowing for symlink attacks.
Package | app-text/tkman on all architectures |
---|---|
Affected versions | < 2.2-r1 |
Unaffected versions | >= 2.2-r1 |
TkMan is a graphical, hypertext manual page and Texinfo browser for UNIX.
Dmitry E. Oboukhov reported that TkMan does not handle the "/tmp/tkman#####" and "/tmp/ll" temporary files securely.
A local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
There is no known workaround at this time.
All TkMan users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/tkman-2.2-r1"
