Description

time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used features that are part of the RFC 2822 format used in a malicious manner. Ordinary, non-malicious input will never encounter this scenario. A limit to the depth of recursion was added in v0.3.47. From this version, an error will be returned rather than exhausting the stack.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

0.3.6 ≤ v < 0.3.47
v < 0.3.47
Affected range stops below 0.3.47, so it looks safe — our inference, not a vendor statement
