| Description: | Summary: Jann Horn discovered a vulnerability in the fuse (Filesystem in Userspace) package in Debian. The fuse package ships an udev rule adjusting permissions on the related /dev/cuse character device, making it world writable. This permits a local, unprivileged attacker to create an arbitrarily-named character device in /dev and modify the memory of any process that opens it and performs an ioctl on it. This in turn might allow a local, unprivileged attacker to escalate to root privileges. Affected Software/OS: fuse on Debian Linux Solution: For the oldstable distribution (wheezy), the fuse package is not affected. For the stable distribution (jessie), this problem has been fixed in version 2.9.3-15+deb8u2. For the testing distribution (stretch), this problem has been fixed in version 2.9.5-1. For the unstable distribution (sid), this problem has been fixed in version 2.9.5-1. We recommend that you upgrade your fuse packages. CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C |
