Claws Mail uses temporary files in an insecure manner, allowing for a symlink attack.
|Package||mail-client/claws-mail on all architectures|
|Affected versions||< 3.0.2-r1|
|Unaffected versions||>= 3.0.2-r1|
Claws Mail is a GTK based e-mail client.
Nico Golde from Debian reported that the sylprint.pl script that is part of the Claws Mail tools creates temporary files in an insecure manner.
A local attacker could exploit this vulnerability to conduct symlink attacks to overwrite files with the privileges of the user running Claws Mail.
There is no known workaround at this time.
All Claws Mail users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=mail-client/claws-mail-3.0.2-r1"
