15 Synopsis
16 ========
17
18 A heap-based buffer overflow in e2fsprogs might allow local attackers
19 to execute arbitrary code.
20
21 Background
22 ==========
23
24 e2fsprogs is a set of utilities for maintaining the ext2, ext3 and ext4
25 file systems.
26
27 Affected packages
28 =================
29
30 -------------------------------------------------------------------
31 Package / Vulnerable / Unaffected

33 1 sys-fs/e2fsprogs < 1.42.12 >= 1.42.12
34
35 Description
36 ===========
37
38 A heap-based buffer overflow was discovered in openfs.c in the
39 libext2fs library in e2fsprogs.
40
41 Impact
42 ======
43
44 A remote attacker could entice a user to use ext2fs library (for
45 example, fsck) on a specially crafted Ext2/3/4 file system possibly
46 resulting in the execution of arbitrary code with the privileges of the
47 process or a Denial of Service condition.
48
49 Workaround
50 ==========
51
52 There is no known workaround at this time.
53
54 Resolution
55 ==========
56
57 All e2fsprogs users should upgrade to the latest version:
58
59 # emerge --sync
60 # emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.42.12"
