Description of problem:
Specific jpg I have can repeatably crash applications that use libjpeg to render
the image (gqview, nautilis etc.).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run gqview or nautilis
2. browse to directory where 'bad' jpeg is located (dload from supplied URL)
Actual Results: Program received signal SIGSEGV, Segmentation fault.
0x405bd5a0 in ycck_cmyk_convert (cinfo=0xc6, input_buf=0x8147870, input_row=1,
output_buf=0xbfffdce4, num_rows=0) at jdcolor.c:278
278 outptr = range_limit[MAXJSAMPLE - (y + Crrtab[cr])]; /* red */
Expected Results: Should just complain about a corrupt jpeg.
libjpeg seems to handle this image okay on RH 7.3.
The URL is dangling. Can't reproduce or fix this without the offending
The URL has been fixed.
I can't reproduce this in FC1 anyway (libjpeg-6b-29).... guess it was
fixed upstream at some point. Feel free to leave it closed if you want.
