CVSS v3.1
Official Description
Memory leak in Gadu-Gadu 7.20 allows remote attackers to cause a denial of service via multiple DCC packets with a code other than 2 and a large size field, which allocates memory for the packet but does not free it after the packet has been dropped.
Technical Analysis
CVE-2005-3888 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.
