Package: clamav
Version: 0.103.2+dfsg-0+deb10u1
Severity: important
Dear Maintainer,
since the latest upgrade to 0.103.2+dfsg-0+deb10u1 clamdscan segfaults
immediately when called with both --fdpass and --multiscan and when the
ExcludePath option is used in clamd.conf. Ubuntu was hit by the same
regression, so I'm referencing the Ubuntu bug report for more details [1].
The issue is fixed upstream [2] and Ubuntu cherry-picked that fix already.
Please consider doing the same for Debian stable.
Thank you!
Regards,
Timo
