adm-zip is vulnerable to Denial of Service (DoS)
75
High Risk
This Affects:
adm-zipTL;DR
adm-zip sizes decompression buffers from the uncompressed-size value declared in a zip entry header before validating it against the compressed data. A minimal crafted archive can declare an enormous uncompressed size, causing the library to commit gigabytes of memory before the CRC check fails. Reading such an archive exhausts memory and denies service on memory-constrained hosts. The fix bounds allocation to a validated size cap and rejects oversized ZIP64 values.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
adm-zip is vulnerable to Denial of Service (DoS) in versions 0.1.3 - 0.6.0.
How to fix this
Upgrade the adm-zip library to the patch version.
