Security Vulnerabilities

crossbeam: MsQueue and SegQueue suffer from double-free

RUSTSEC-2018-0009

Even if an element is popped from a queue, crossbeam would run its destructor inside the epoch-based garbage collector. This is a source of double frees.

The flaw was corrected by wrapping elements inside queues in a ManuallyDrop.

Thanks to @c0gent for reporting the issue.

regex: Regexes with large repetitions on empty sub-expressions take a very long time to parse

RUSTSEC-2022-0013

The 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.

Overview

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.

Affected versions

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.

Mitigations

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.

Acknowledgements

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.

owning_ref: Multiple soundness issues in `owning_ref`

RUSTSEC-2022-0040

  • OwningRef::map_with_owner is unsound and may result in a use-after-free.
  • OwningRef::map is unsound and may result in a use-after-free.
  • OwningRefMut::as_owner and OwningRefMut::as_owner_mut are unsound and may result in a use-after-free.
  • The crate violates Rust's aliasing rules, which may cause miscompilations on recent compilers that emit the LLVM noalias attribute.

safer_owning_ref is a replacement crate which fixes these issues. No patched versions of the original crate are available, and the maintainer is unresponsive.
