Official Description
Multiple integer overflows in the in_avi.dll plugin in Winamp before 5.623 allow remote attackers to execute arbitrary code via an AVI file with a crafted value for (1) the number of streams or (2) the size of the RIFF INFO chunk, leading to a heap-based buffer overflow.

CVE-2011-3834 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
