All,
We wanted to bring to your attention an issue that we have been made aware of in ClamAV 0.97.5. As part of this release, we tightened the malformed compression checks in LZX compressed files. CAB, CHM and Install Shield file formats may use this compression. In previous versions of ClamAV, these files would be passed as "OK" when the decompression failed. ClamAV 0.97.5 will respond with a CL_EFORMAT error instead. In some environments, this level of checking may be inappropriate. We are currently reviewing the situation and evaluating what, if any, changes are appropriate. A bug has been created so you can follow our work: https://bugzilla.clamav.net/show_bug.cgi?id=5252 If you have any questions, please let us know.
