A vulnerability classified as critical has been found in AVS Audio Converter 8.2.1. This affects an unknown function. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability.
The weakness was shared 08/22/2016 by ZwX as 1920 as not defined advisory (Website). The advisory is shared at vulnerability-lab.com. Technical details are unknown but a public exploit is available. The advisory points out:
A buffer overflow vulnerability has been discovered in the official software AVS Audio Converter V8.2.1. The vulnerability allows local attackers to overwrite registers to compromise the local software process. Vulnerability classic buffer overflow is in the AVS Audio Converter. An attacker can manipulate the bit EIP register to execute the next instruction of their choice. Attackers can eg execute arbitrary code with the privileges of the process. The attacker has a large unicode string to crush the EIP register process. Finally, the attacker is able to process the takeover by a crushing of the active program process to compromise the computer system.
A public exploit has been developed by ZwX in Perl and been published immediately after the advisory. The exploit is shared for download at seclists.org. It is declared as proof-of-concept. The code used by the exploit is:
#!/usr/bin/perl my $Buff = "x41" x 9000; open(MYFILE,'>>poc.txt'); print MYFILE $Buff; close(MYFILE); print "Local BOF PoC by ZwXn";
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
