2009年9月22日 · The best-known zip bomb, 42.zip, expands to a formidable 4.5 PB if all six of its layers are recursively unzipped, but a trifling 0.6 MB at the top layer. Zip quines, like those of Ellingsen and Cox, which contain a copy of themselves and thus expand infinitely if recursively unzipped, are likewise perfectly safe to unzip once."

I just read about zip bombs, i.e. zip files that contain very large amount of highly compressible data (00000000000000000...). When opened they fill the server's disk. How can I detect a zip file...

2018年3月31日 · In order to prevent some types of denial-of-service-attacks, it has functionality when opening Zip-files to not read files which expand a lot and thus could be used to overwhelm the main memory by providing a small malicious file which explodes when uncompressed into memory. Apache POI calls this zip-bomb-protection.

2019年5月8日 · I have a large ~10GB zip file that was created using the standard Windows method (right click, select "send to compressed (zipped) folder"). I am able to unzip it just file on my Macbook. I'm trying to unzip it on an EC2 machine. I know the file is a zip file because when I run file file.zip it says: file.zip: Zip archive data, at least v2.0 to ...

"Zip bomb" is a term used for an attack vector where a small zip file expands to a very large uncompressed file and thus can cause issues like exhausting memory or disk space. Usually such zips are created with the intent of causing a denial of service attack on systems that receive zip files from external sources.

2022年6月2日 · Sonarqube reports Security Hotspots vulnerability as prone to "Zip Bomb" security issue with message "Make sure that expanding this archive file is safe here" in the line "ZipEntry entry = zipIn.getNextEntry();". As a solution, trying to use Apache Commons Compress version 1.21 library which handles Zip Bomb starting from version 1.17.

Caused by: java.io.IOException: Zip bomb detected! The file would exceed certain limits which usually indicate that the file is used to inflate memory usage and thus could pose a security risk. You can adjust these limits via setMinInflateRatio() and setMaxEntrySize() if you need to work with files which exceed these limits.

2012年11月29日 · This is related to the question about zip bombs, but having gzip or bzip2 compression in mind, e.g. a web service accepting .tar.gz files. Python provides a handy tarfile module that is convenient...

Caused by: java.io.IOException: Zip bomb detected! The file would exceed the max. ratio of compressed file size to the size of the expanded data. This may indicate that the file is used to inflate memory usage and thus could pose a security risk.

2020年11月26日 · I downloaded MOT17 dataset and when I try to unzip it using: $ unzip MOT17.zip I get this: error: not enough memory for bomb detection error: invalid zip file with overlapped components (possible zip
