7 The following security holes affect Tails 0.6.2.
9 We **strongly** urge you to [[upgrade to Tails 0.7|news/version_0.7]]
10 in case you are still using an older version.
14 # Incomplete "erase memory on shutdown" feature
16 As an [[external audit
17 demonstrated|security/audits/Blackhat_De-Anonymizing_Live_CDs]], the
18 "erase memory on shutdown" feature, as implemented in Tails 0.6.2 and
19 older, does not erase as much memory as it could. More specifically:
21 1. Parts of the memory that are still allocated at shutdown time are
22 not erased and can be recovered after shutdown; this includes the
23 entire in-memory filesystem (associated meta-data, content of files
24 created or modified since boot).
25 2. Partial recovery of deleted file names and their meta-data is also
28 This discovery lead to a brand new implementation of the memory
29 erasure feature that is shipped in Tails 0.7. As a bonus, the memory
30 is now also erased when the boot media is physically removed.
