2.1
CVSS v3.1
Official Description
cipher.c in the Cipher API in libpurple in Pidgin before 2.7.10 retains encryption-key data in process memory, which might allow local users to obtain sensitive information by reading a core file or other representation of memory contents.
Technical Analysis
CVE-2011-4922 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
