Description:
A security issue has been reported in pam_krb5, which can be exploited by malicious, local users to bypass certain security restrictions.
The security issue is caused due to pam_krb5 not correctly restricting users from reusing the existing credentials of another user. This can be exploited to e.g. switch into another user's account by setting the "KRB5CCNAME" variable to point to the credentials cache of the target user.
Successful exploitation requires that the "existing_ticket" option is enabled.
The security issue is reported in versions 2.2.0 to 2.2.25, 2.3.0, and 2.3.1. Other versions may also be affected.
