RUSTSEC-2018-0006
No affected components available
Affected versions of this crate did not prevent deep recursion while deserializing data structures.
This allows an attacker to make a YAML file with deeply nested structures that causes an abort while deserializing it.
The flaw was corrected by checking the recursion depth.
Note: clap 2.33 is not affected by this because it uses yaml-rust
in a way that doesn't trigger the vulnerability. More specifically:
-
The input to the YAML parser is always trusted - is included at compile time via
include_str!. -
The nesting level is never deep enough to trigger the overflow in practice (at most 5).
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
