Summary: iconv(3) doesn't handle invalid sequence properly
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: yukihiro.nakadaira@gmail.com
When converting from cp932, iconv() doesn't handle invalid sequence properly.
See the following code.
iconv() returns -1 but inbuf is consumed.
I think it is the same issue with this.

#include <stdio.h>
#include <errno.h>
#include <iconv.h>
int main()
{
iconv_t cd;
char in[] = "\x83\xd9";
char out[256];
char *inbuf;
size_t inbytesleft;
char *outbuf;
size_t outbytesleft;
size_t ret;
inbuf = in;
inbytesleft = sizeof(in) - 1;
outbuf = out;
outbytesleft = sizeof(out);
cd = iconv_open("utf-8", "cp932");
ret = iconv(cd, &inbuf, &inbytesleft, &outbuf, &outbytesleft);
iconv_close(cd);
printf("result: %ld %d %ld %d\n", ret, errno, inbytesleft, inbuf[0]);
/*
* result: -1 84 0 0 (84=EILSEQ)
*
* Error is returnd but inbuf is consumed.
*
* \x83\xd9 is valid shift-jis sequence but no character is assigned
* to it.
*/
return 0;
}
