Description David Walser 2018-09-11 23:28:29 CEST
Fedora has issued an advisory today (September 11):

The issue is fixed upstream in 4.1.

Mageia 5 is also affected.
Comment 1 Marja Van Waes 2018-09-12 20:01:23 CEST
Assigning to all packagers collectively, since the registered maintainer for this package is currently unavailable.

Note that, after council's decision last night, this cannot be fixed in Mga5.

Comment 3 David GEIGER 2018-09-23 20:03:41 CEST
for an update in a release distro you should use "%define subrel" and not bump the rel.

Not in the case cauldron has an higher version of the software, as for here.
Comment 5 Arusekk K 2018-09-23 22:52:34 CEST

Updated iniparser packages fix security vulnerability:

A flaw was found in iniparser version prior to 4.1. A stack buffer underflow in the function iniparser_load() in iniparser.c file which can be triggered by parsing a file that containing a zero-byte. This vulnerability may allow an attacker to cause a Denial of Service (DoS).


Updated packages in core/updates_testing:

from iniparser-3.1-8.mga6.src.rpm

Incorrect.  You should use a subrel and not bump the rel, even in that case.

$ uname -a
Linux localhost 4.14.78-desktop-1.mga6 #1 SMP Sun Oct 21 20:31:12 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The following 2 packages are going to be installed:

- lib64iniparser-devel-3.1-8.mga6.x86_64
- lib64iniparser0-3.1-8.mga6.x86_64


- I installed gcc
- found an example program that calls iniparser (see attached).

Compile and link via this command:

$ gcc iniexample.c -lm /usr/lib64/libiniparser.so.0 -o iniexamp

execute the program by

$ ./iniexamp

by default the program produces a file called example.ini.

You can cat the file by:

$ cat example.ini

I also tried it against an empty file

$ touch empty.ini

$ ./iniexamp empty.ini

It processes the empty file

I tried echo null to the file (need some input here oh echoing null)

$ echo $'\0' > empty.ini

Ran the program again - no issues

The library works

The following 2 packages are going to be installed:

- libiniparser-devel-3.1-8.mga6.i586
- libiniparser0-3.1-8.mga6.i586

37KB of additional disk space will be used.

26KB of packages will be retrieved.

Is it ok to continue?



$ gcc iniexample.c -lm /usr/lib/libiniparser.so.0 -o iniexamp
