-Subject: [PATCH] iconv: Accept redundant shift sequences in IBM1364 [BZ
- #26224]
-
-The IBM1364, IBM1371, IBM1388, IBM1390 and IBM1399 character sets
-share converter logic (iconvdata/ibm1364.c) which would reject
-redundant shift sequences when processing input in these character
-sets.  This led to a hang in the iconv program (CVE-2020-27618).
-
-This commit adjusts the converter to ignore redundant shift sequences
-and adds test cases for iconv_prog hangs that would be triggered upon
-their rejection.  This brings the implementation in line with other
-converters that also ignore redundant shift sequences (e.g. IBM930
-etc., fixed in commit 692de4b3960d).
