2019-10-03mount.cifs: Fix double-free issue when mounting with setuid rootPaulo Alcantara (SUSE)1-2/+4
It can be easily reproduced with the following: # chmod +s `which mount.cifs` # echo "//localhost/share /mnt cifs \ users,username=foo,password=XXXX" >> /etc/fstab # su - foo $ mount /mnt free(): double free detected in tcache 2 Child process terminated abnormally. The problem was that check_fstab() already freed orgoptions pointer and then we freed it again in main() function.

2019-08-07Zero fill the allocated memory for a new ACEmisku1-1/+1
Fixes a bug inside a call to `verify_ace_flag`. When a flag string (char*) passed as a first parameter is "0x0", the final flag value (the second parameter - the value of a pointer to uint8_t) is not modified at all and contains the original memory contents == trash.
2019-08-07mount.cifs.c: fix memory leaks in main funcJiawen Liu1-1/+9
In mount.cifs module, orgoptions and mountpoint in the main func point to the memory allocated by func realpath and strndup respectively. However, they are not freed before the main func returns so that the memory leaks occurred. The memory leak problem is reported by LeakSanitizer tool. LeakSanitizer url: "https://github.com/google/sanitizers" Here I free the pointers orgoptions and mountpoint before main func returns.
