Description Guilherme de Almeida Suckevicz 2021-07-13 17:21:13 UTC

When reading a specially crafted 7Z archive, the construction of the list of codecs that decompress an entry can result in an infinite loop. This could be used to mount a denial of service attack against services that use Compress' sevenz package.

Comment 3 Garrett Tucker 2021-07-16 20:45:19 UTC

After analysis, a Denial of Service attack is possible via an infinite loop caused by a crafted 7Z archive. The construction of the list of codecs for decompression did not check for usage of the same codec more than once in the codec chain. Thus a specially crafted archive could force an infinite loop impacting availability of a system.

This flaw has been fixed in Version 1.21
