Description

A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different backends for resolving host names, selected at build time. If it is built to use the synchronous resolver, it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this, libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore crash or otherwise misbehave.

Affected configurations

• haxx curl (< 8.1.0) • apple macos (>= 11.0 < 11.7.9) • apple macos (>= 12.0 < 12.6.8) • apple macos (>= 13.0 < 13.5) • netapp clustered data ontap • netapp ontap antivirus connector • netapp h300s firmware • netapp h500s firmware • netapp h700s firmware • netapp h410s firmware
