Package: release.debian.org
Version: 5.3.3-1
Severity: normal
Tags: bullseye
User: [email protected]
Usertags: pu
X-Debbugs-Cc: [email protected]
Control: affects -1 + src:cryptmount
[ Reason ]
When cryptmount is passed invalid command-line arguments, it is likely
to crash with a SEGV error due to inappropriately zeroed memory passed
to getopt_long().
[ Impact ]
The absence of error-messages when invalid command-line arguments are supplied
affects usability. The use of uninitialized memory with a setuid binary is,
potentially, a security risk.
[ Tests ]
The fix involves a single-line change to replace a call to malloc()
with one to calloc(). This has been tested manually on invalid command-line
arguments,
and the upstream "mudslinger" test-suite has been used for regression tests
across a wide range of usage scenarios.
[ Risks ]
The proposed change has very little risk of side-effects.
[ Checklist ]
[x] *all* changes are documents in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in bullseye
[x] the issue is verified as fixed in unstable
[ Changes ]
A call to malloc() prior to using getopt_long() has been replaced by
a similar call to calloc().
