The remote Debian host is missing a security-related update.
Jose Duart of the Google Security Team discovered a buffer overflow in e2fsprogs, a set of utilities for the ext2, ext3, and ext4 file systems. This issue can possibly lead to arbitrary code execution if a malicious device is plugged in, the system is configured to automatically mount it, and the mounting process chooses to run fsck on the device's malicious filesystem. - CVE-2015-0247 Buffer overflow in the ext2/ext3/ext4 file system open/close routines. - CVE-2015-1572 Incomplete fix for CVE-2015-0247.
Upgrade the e2fsprogs packages. For the stable distribution (wheezy), these problems have been fixed in version 1.42.5-1.1+deb7u1. For the upcoming stable (jessie) and unstable (sid) distributions, these problems will be fixed soon.
