Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

DotNetZip versions 1.10.1 through 1.16.0 have a directory traversal flaw in archive entry extraction that can allow a remote attacker to execute arbitrary code. The source gives few details on the conditions required. No fixed DotNetZip version is listed; for ProDotNetZip, versions before 1.19.0 are affected, so upgrade to 1.19.0.
