Description: Ubuntu 11.04
Release: 11.04
When reading dvd 'The Express' via dvdbackup -I, I get a core dump:
*** glibc detected *** dvdbackup: free(): invalid next size (normal): 0x0000000002ccef70 ***
Using Valgrind, I was able to track down the culprit, in the file ifo_read.c, function ifoRead_TT_SRPT, where a structure array is allocated, but another variable, extracted from the DVD info determines the lenght of the array, resulting in read/writes beyond the array. I truncate the read, but perhaps a better solution would be to expand the malloc to include the data off the DVD. I believe that, however could lead to out of memory errors if the DVD data was bad/invalid.
With the applied patch, dvdbackup no longer segfaults. |

SRU Request:
Impact: Oneiric cannot read certain dvds, including "The Express".
Development fix: This is fixed in Precise with the minimal patch provided in this bug.
Stable fix: An identical minimal patch has been applied to the Oneiric package
Test Case: Unfortunately, someone needs to try playing the "The Express" DVD to test this updated package
Regression potential: Although unlikely, this patch may prevent other DVDs from playing, in which case the patch can be backed out.
