An insecure temporary file usage has been reported in aview, leading to symlink attacks.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/aview | * | < 1.3.0_rc1-r1 | >= 1.3.0_rc1-r1 |
aview is an ASCII image viewer and animation player.
Dmitry E. Oboukhov reported that aview uses the "/tmp/aview$$.pgm" file in an insecure manner when processing files.
A local attacker could perform symlink attacks to overwrite arbitrary files on the system with the privileges of the user running the application.
There is no known workaround at this time.
All aview users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/aview-1.3.0_rc1-r1"
