Description

Mail Notification contains a flaw that may allow a remote denial of service. The issue is triggered when an unparsable URI is passed to the soup_context_get() function in the Gmail module causing soup_context_get() to return a null value which, with certain libsoup configurations, will lead to a null pointer indirection and will result in loss of availability for the service.

Classification

Location: Remote/Network Access Required
Attack Type: Denial of Service
Impact: Loss of Availability
Exploit: Exploit Unknown
Disclosure: OSVDB Verified

Solution

Upgrade to version 0.7.0 or higher, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): Do not monitor a Gmail mailbox. If you want to ensure that the faulty code will not be used, reinstall Mail Notification using the following commands:
$ ./configure --disable-gmail
$ make
$ make install
