Comment 2 Mike Rambo 2018-11-02 17:52:57 CET

Patched package uploaded for cauldron and Mageia 6.

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

Updated opencc package fixes security vulnerability:

It was discovered that opencc contained an out of bounds pointer in BinaryDict.cpp which could lead to segment fault and a Denial of Service (CVE-2018-16982).

Comment 3 Len Lawrence 2018-11-06 16:39:12 CET

Mageia 6, x86_64

CVE-2018-16982
https://github.com/BYVoid/OpenCC/issues/303
$ opencc_dict -i keyoffsetPOC -o temp.txt -f ocd -t text
Segmentation fault (core dumped)
$ opencc_dict -i ValueOffsetPOC -o temp.txt -f ocd -t text
Segmentation fault (core dumped)

Clean update of the packages.

Ran the POC tests again.

$ opencc_dict -i keyoffsetPOC -o temp.txt -f ocd -t text
Invalid format: Invalid OpenCC binary dictionary (keyOffset)
$ opencc_dict -i ValueOffsetPOC -o temp.txt -f ocd -t text
Invalid format: Invalid OpenCC binary dictionary (valueOffset)

opencc has a --help facility but not knowing anything about input file formats I left this alone.

Clean update and positive POC tests so this is OK for 64-bits.
