[BlueOnyx:21691] Security Issue in ClamAV

[Gerrit Haas]

Hi all,

There recently has been a security issue with Clamav:

http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html

German:
https://www.heise.de/security/meldung/Jetzt-patchen-Angriffe-auf-Viren-Scanner-ClamAV-3951801.html

Which could lead to execution of malicious 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 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.
<<<

Everything newer than 0.99.3 seems to be fixed.

Will there be a fix for versions that are not under maintenance?



With kind regards 
Gerrit Haas
