http: Integer Overflow in HeaderMap::reserve() can cause Denial of ServiceHeaderMap::reserve() used usize::next_power_of_two() to calculate the increased capacity.
However, next_power_of_two() silently overflows to 0 if given a sufficiently large number
in release mode.
If the map was not empty when the overflow happens,
the library will invoke self.grow(0) and start infinite probing.
This allows an attacker who controls the argument to reserve()
to cause a potential denial of service (DoS).
The flaw was corrected in 0.1.20 release of http crate.
http: HeaderMap::Drain API is unsoundAffected versions of this crate incorrectly used raw pointer, which introduced unsoundness in its public safe API.
Failing to drop the Drain struct causes double-free, and it is possible to violate Rust's alias rule and cause data race with Drain's Iterator implementation.
The flaw was corrected in 0.1.20 release of http crate.
regex: Regexes with large repetitions on empty sub-expressions take a very long time to parseThe Rust Security Response WG was notified that the regex crate did not
properly limit the complexity of the regular expressions (regex) it parses. An
attacker could use this security issue to perform a denial of service, by
sending a specially crafted regex to a service accepting untrusted regexes. No
known vulnerability is present when parsing untrusted input with trusted
regexes.
This issue has been assigned CVE-2022-24713. The severity of this vulnerability
is "high" when the regex crate is used to parse untrusted regexes. Other uses
of the regex crate are not affected by this vulnerability.
The regex crate features built-in mitigations to prevent denial of service
attacks caused by untrusted regexes, or untrusted input matched by trusted
regexes. Those (tunable) mitigations already provide sane defaults to prevent
attacks. This guarantee is documented and it's considered part of the crate's
API.
Unfortunately a bug was discovered in the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing, and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted regexes.
All versions of the regex crate before or equal to 1.5.4 are affected by this
issue. The fix is include starting from regex 1.5.5.
We recommend everyone accepting user-controlled regexes to upgrade immediately
to the latest version of the regex crate.
Unfortunately there is no fixed set of problematic regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability. Because of this, we do not recommend denying known problematic regexes.
We want to thank Addison Crump for responsibly disclosing this to us according to the Rust security policy, and for helping review the fix.
We also want to thank Andrew Gallant for developing the fix, and Pietro Albini for coordinating the disclosure and writing this advisory.
