This release is a security release and is recommended for all ClamAV users. Please see details below:
The ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing operations. If successfully exploited, the ClamAV software could allow a variable pointing to the mail body which could cause a used after being free (use-after-free) instance which may lead to a disruption of services on an affected device to include a denial of service condition.
The ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to a lack of input validation checking mechanisms during certain mail parsing functions. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition on an affected device.
ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device.
The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause a buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code.
ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device.
The vulnerability is due to improper input validation checking mechanisms in mew packet files sent to an affected device. A successful exploit could cause a heap overflow condition when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device.
ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to improper input validation checking mechanisms of .tar (Tape Archive) files sent to an affected device. A successful exploit could cause a buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device.
ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device.
The vulnerability is due to improper input validation checking mechanisms in the message parsing function on an affected system. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. This action could cause a buffer overflow condition when ClamAV scans the malicious email, allowing the attacker to potentially cause a DoS condition or execute arbitrary code on an affected device.
ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to improper input validation checking mechanisms during certain mail parsing functions of the ClamAV software. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted email to the affected device. An exploit could trigger a NULL pointer dereference condition when ClamAV scans the malicious email, which may result in a DoS condition.
Also included are 2 minor fixes to properly detect openssl install locations on FreeBSD 11, and prevent false warnings about zlib 1.2.1# version numbers.

I can't install this update due to a checksum error:
Prüffehler bei Verarbeitung: file /var/lib/clamav/bytecode.cvd conflicts between attempted installs of clamav-db-0.99.2-3.el6.x86_64 and clamav-data-0.99.3-1.el6.noarch file /var/lib/clamav/daily.cvd conflicts between attempted installs of clamav-db-0.99.2-3.el6.x86_64 and clamav-data-0.99.3-1.el6.noarch file /var/lib/clamav/main.cvd conflicts between attempted installs of clamav-db-0.99.2-3.el6.x86_64 and clamav-data-0.99.3-1.el6.noarch
karma: -1
This gives errors like
[LibClamAV] cli_loadldb: logical signature for Win.Trojan.ssid18332-1 uses PCREs but support is disabled, skipping
when a scan is run. This is a regression as clamconf | grep Optional gives
Optional features supported: MEMPOOL IPv6 AUTOIT_EA06 BZIP2 LIBXML2 ICONV JIT
for this version but clamav-0.99.2-2.el6 gave
Optional features supported: MEMPOOL IPv6 AUTOIT_EA06 BZIP2 LIBXML2 PCRE ICONV JIT
Bodhi is disabling automatic push to stable due to negative karma. The maintainer may push manually if they determine that the issue is not severe.

Apologies if this is inappropriate to ask here.....but are there any plans/work in-progress to fix these issues with this version of clamav for EPEL 6 so we can get this important security update released into production?
Thank you!
This update has reached 14 days in testing and can be pushed to stable now if the maintainer wishes
This update has been obsoleted by clamav-0.99.3-8.el6.
If it passes tests, can this package be pushed to stable EPEL?
@anonymous please after testing clamav-0.99.3-8.el6 (it is in updates-testing) login and give positive karma in https://bodhi.fedoraproject.org/updates/clamav-0.99.3-8.el6
