CVSS v3.1
Official Description
Integer overflow in Skype client before 1.4.x.84 on Windows, before 1.3.x.17 on Mac OS, before 1.2.x.18 on Linux, and 1.1.x.6 and earlier allows remote attackers to cause a denial of service (crash) via crafted network data with a large Object Counter value, which leads to a resultant heap-based buffer overflow.
Technical Analysis
CVE-2005-3267 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.
