Comment 3 David Walser 2020-08-06 21:02:10 CEST

Advisory:
========================

Updated python-rtslib packages fix security vulnerability:

Open-iSCSI rtslib-fb through 2.1.72 has weak permissions for
/etc/target/saveconfig.json because shutil.copyfile (instead of shutil.copy) is
used and thus permissions are not preserved upon editing. An adversary with
prior access to /etc/target/saveconfig.json could access a later version,
resulting in a loss of integrity depending on their permission settings
(CVE-2020-14019).

MGA7-64 Plasma on Lenovo B50
No installation issues.
No previous updates, so try....
# urpmq --whatrequires-recursive python-rtslib
python-rtslib
python-rtslib-doc
targetcli

Insstalled targetcli and then:
# strace -o pthrtslib.txt targetcli

In targetcli I tried:
/> help

GENERALITIES

This is a shell in which you can create, delete and configure
configuration objects.

Configuration saved to /etc/target/saveconfig.json

Then checked the trace and found a.o.
stat("/usr/lib/python2.7/site-packages/targetcli/rtslib_fb", 0x7ffc4bc33aa0) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib/python2.7/site-packages/targetcli/rtslib_fb.so", O_RDONLY) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib/python2.7/site-packages/targetcli/rtslib_fbmodule.so", O_RDONLY) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib/python2.7/site-packages/targetcli/rtslib_fb.py", O_RDONLY) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/usr/lib/python2.7/site-packages/targetcli/rtslib_fb.pyc", O_RDONLY) = -1 ENOENT (No such file or directory)
So, it looks it did something usefull.
