Rating: Highly critical



Sergio Alvarez has reported some vulnerabilities in NOD32 Antivirus, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.


1) A race-condition error when processing CAB archives can be exploited to cause a heap corruption when e.g. scanning a specially crafted CAB archive.


Successful exploitation may allow execution of arbitrary code.


2) A divide-by-zero error when processing Aspack and FSG packed files can be exploited to e.g. crash the application via a specially crafted Aspack or FSG packed file.


3) An integer-overflow error when processing Aspack packed files can be exploited to cause an infinite loop and consume large amounts of CPU resources via a specially crafted Aspack packed file.


The vulnerabilities are reported in versions prior to update v.2.2289.



Apply update v.2.2289 or later.
