CVE-2020-26235— Segmentation fault in Rust time crate

Quick assessment

Affected
time-rs time
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Rust是一款通用、编译型编程语言。 Rust time crate 0.2.7版本至0.2.23版本存在安全漏洞，该漏洞源于unix操作系统可能会因为在特定环境下解引用一个悬浮指针而出现段故障。这要求用户在与受影响函数不同的线程中设置任何环境变量。受影响的函数有：time::UtcOffset::local_offset_at, time::UtcOffset::try_local_offset_at, time::UtcOffset::current_local_offset, time::UtcOf

Vulnerability Title
Segmentation fault in Rust time crate
Source: CVE Program / CVE List V5
Vulnerability Description
In Rust time crate from version 0.2.7 and before version 0.2.23, unix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires the user to set any environment variable in a different thread than the affected functions. The affected functions are time::UtcOffset::local_offset_at, time::UtcOffset::try_local_offset_at, time::UtcOffset::current_local_offset, time::UtcOffset::try_current_local_offset, time::OffsetDateTime::now_local and time::OffsetDateTime::try_now_local. Non-Unix targets are unaffected. This includes Windows and wasm. The issue was introduced in version 0.2.7 and fixed in version 0.2.23.
