CVE-2010-3874: Buffer Overflow
First published: Thu Nov 04 2010(Updated: )
Description of problem: In bcm_connect() (in net/can/bcm.c), there is the following code: sprintf(bo->procname, "%p", sock); "procname" is a 9-byte char array. On 64-bit platforms, up to 17 bytes may be copied into the buffer. Fortunately, structure padding will most likely prevent this from being a problem, except for the trailing NULL byte, which may overwrite the first byte of the next heap object.
