CVE-2022-21658 |
Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency. The Rust Security Response WG was notified that the `std::fs::remove_dir_all` standard library function is vulnerable a race condition enabling symlink following (CWE-363). An attacker could use this security issue to trick a privileged program into deleting files and directories the attacker couldn't otherwise access or delete. Rust 1.0.0 through Rust 1.58.0 is affected by this vulnerability with 1.58.1 containing a patch. Note that the following build targets don't have usable APIs to properly mitigate the attack, and are thus still vulnerable even with a patched toolchain: macOS before version 10.10 (Yosemite) and REDOX. We recommend everyone to update to Rust 1.58.1 as soon as possible, especially people developing programs expected to run in privileged contexts (including system daemons and setuid binaries), as those have the highest risk of being affected by this. Note that adding checks in your codebase before calling remove_dir_all will not mitigate the vulnerability, as they would also be vulnerable to race conditions like remove_dir_all itself. The existing mitigation is working as intended outside of race conditions. Published: January 20, 2022; 1:15:07 PM -0500 |
V4.0:(not available) V3.1: 6.3 MEDIUM V2.0: 3.3 LOW |
CVE-2021-29922 |
library/std/src/net/parser.rs in Rust before 1.53.0 does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation.

V4.0:(not available) V3.1: 9.1 CRITICAL V2.0: 6.4 MEDIUM |
CVE-2020-36323 |
In the standard library in Rust before 1.52.0, there is an optimization for joining strings that can cause uninitialized bytes to be exposed (or the program to crash) if the borrowed string changes after its length is checked. Published: April 14, 2021; 3:15:12 AM -0400 |
V4.0:(not available) V3.1: 8.2 HIGH V2.0: 6.4 MEDIUM |
CVE-2021-28879 |
In the standard library in Rust before 1.52.0, the Zip implementation can report an incorrect size due to an integer overflow. This bug can lead to a buffer overflow when a consumed Zip iterator is used again. Published: April 11, 2021; 4:15:12 PM -0400 |
V4.0:(not available) V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2021-28878 |
In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked() more than once for the same index (under certain conditions) when next_back() and next() are used together. This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait. Published: April 11, 2021; 4:15:12 PM -0400 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0: 4.3 MEDIUM |
CVE-2021-28877 |
In the standard library in Rust before 1.51.0, the Zip implementation calls __iterator_get_unchecked() for the same index more than once when nested. This bug can lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait. Published: April 11, 2021; 4:15:12 PM -0400 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2021-28876 |
In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait. Published: April 11, 2021; 4:15:12 PM -0400 |
V4.0:(not available) V3.1: 5.3 MEDIUM V2.0: 4.3 MEDIUM |
CVE-2021-28875 |
In the standard library in Rust before 1.50.0, read_to_end() does not validate the return value from Read in an unsafe context. This bug could lead to a buffer overflow. Published: April 11, 2021; 4:15:12 PM -0400 |
V4.0:(not available) V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2020-36317 |
In the standard library in Rust before 1.49.0, String::retain() function has a panic safety problem. It allows creation of a non-UTF-8 Rust string when the provided closure panics. This bug could result in a memory safety violation when other string APIs assume that UTF-8 encoding is used on the same string. Published: April 11, 2021; 4:15:12 PM -0400 |
