If such a simple calculation cannot be written naively, what other unexpected results are unsigned values going to introduce in a code base of any size. Now I am starting to wonder how many percent of CVEs have sloppy type conversion, and magic values (which can be avoided by using enum variants) as the root cause ?Ī naive mean calculation in C(++) ( ) is flawed in a way that is not readily apparent without execution (unlike accumulator overflow with large sums) and generates no warnings. The Microsoft Research blog recently pointed out that a large percentage of CVEs have memory safety issues as root cause. Signed values are cast back and forth to unsigned, and it is not very surprising that the footgun goes off when the magic "(unsigned)-1" value is passed to the kernel.

Having gotten used to Rusts stricter type checking, reading the sudo & kernel source code just hurts my head a little bit.

#Cve 2019 14287 exploit 32 bit

Mind you that gid_t is defined to be an unsigned 32 bit integer but 0xffffffff has the magic property that setgid does nothing and whatever you want to run then executes with root privileges that are inherited from sudos suid root. But additionally the Linux kernel syscall code have these lines to effectuate the setgid(): The sudo source code goes out of its way to parse a negative value before it is cast into a an unsigned.

If you need to input a password to run sudo -l then the script will not work if you don’t provide a password with the argument -s. cve_update.sh Providing password ( Important)

#Cve 2019 14287 exploit update

To update the CVE database : run the following script. Very often, a sudo version might be vulnerable but the specific conditions must be met for exploitation. It is worth noting that when using the -c argument, the CVEs identified are only based on the sudo version in used.
