A vulnerability in the kwallet-pam module in KDE KWallet could allow a local attacker to gain unauthorized access to arbitrary files on a targeted system.
The vulnerability is due to improper security restrictions imposed by the affected software. The kwallet-pam module of the software performs file writing and permission changing operations as root. An attacker could exploit this vulnerability by conducting a symbolic link attack on the targeted system. A successful exploit could allow the attacker to access sensitive, privileged files on the system, which could be used to conduct further attacks.
The KDE Project has confirmed the vulnerability and released software updates.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement could reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to access local systems.
Administrators are advised to allow only privileged users to access administration or management systems.
Administrators are advised to monitor critical systems.
