Description:
Description:
A buffer overflow was detect in chunk_free_object function in base/gsmchunk.c
source file. This particular vulnerablity can only be exploited if ghostxps is
compiled with DEBUG flags.
Affected code:
723 memset((byte *)(new_free) + SIZEOF_ROUND_ALIGN(chunk_freelist_node_t),
0xf1,
724 new_free->size - SIZEOF_ROUND_ALIGN(chunk_freelist_node_t));
