CVE-2021-36090

Apache Commons Compress 1.0 to 1.20 denial of service vulnerability

EPSS 13.3%CWE-130
In short

A malicious ZIP file can trick Apache Commons Compress into using massive amounts of memory, causing the application to crash even with tiny files. This allows attackers to disable services by sending specially crafted ZIP archives.

Technical detail

CWE-130 vulnerability in Commons Compress versions 1.0-1.20 allows remote attackers to cause denial of service via specially crafted ZIP archives that trigger excessive memory allocation during decompression. Attack vector is network-based (malicious ZIP file), with no authentication required; impact is service unavailability through out-of-memory conditions.

Summary generated and translated by AI from the official description.
When reading a specially crafted ZIP archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs. This could be used to mount a denial of service attack against services that use Compress' zip package.
