[squid-users] ClamAV crash in eCAP Adapter

[Rafael Akchurin]

Hello everyone,

May I ask for your experiences with the latest update of ClamAV with eCAP adapter enabled. Running Squid 5.7 on Ubuntu 20.04.
Starting from today (01-March-2023) the following crash stops Squid process.

#0  0x00007fab13a44ff0 in cli_bm_scanbuff () from /lib/x86_64-linux-gnu/libclamav.so.9

#15 0x00005611993a8ef6 in main ()

Am I correct to think the crash might be related to some definition file update issued by ClamAV team?

Already tried re-download of the definition files using freshclam, but without any success.
Disabling eCAP adapter solves the problems but I would rather find out why it crashes.

Best regards,
Rafael
