According to Secunia: "Two vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service). 1) Input passed via the "id" parameter when parsing MIME headers is not properly sanitised before being used to create local files. This can be exploited to e.g. overwrite the anti-virus signature file via directory traversal attacks, preventing malware from being detected. 2) An file descriptor leak error in the processing of CAB files can be exploited to e.g. prevent legitimate users from sending out valid archives via a specially crafted CAB file with a cabinet header containing a record length of zero." Please update the FC-6 package to version 0.90 to fix these. Thanks.
This update will also fix the following warning in the logs: Last Status: WARNING: Your ClamAV installation is OUTDATED! WARNING: Local version: 0.88.7 Recommended version: 0.90 DON'T PANIC!

CVEs should be fixed by 0.88.7-2; freshclam warning is only a warning and I do not plan to update version FC-5/6 to 0.90
Hmmm, I regard this as quite lousy...
Why? Maintenance is not about always pushing out the absolute latest version. If you have a compelling argument to make regarding why all machines should get 0.90 then please make it. If you have questions about why 0.90 is not appropriate to push out to all machines then please ask them. The bottom line is that it is the maintainer's decision. You can always grab the devel SRPM or check the source out from CVS and build it yourself if you disagree.
Enrico, there are references and patches related to CVE-2007-0899 in the 0.88.7-2 update, however I'm not able to find any real info about that CVE anywhere; in MITRE it's just reserved, and in NVD it's empty. Any links to publicized info about the issue?
I took it from the Debian changelog | [CVE-2007-0899] Possible heap overflow in libclamav/fsg.c I do not have more details.
