Description Guilherme de Almeida Suckevicz 2021-07-13 17:25:24 UTC

When reading a specially crafted 7Z 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' sevenz package.

Comment 3 Garrett Tucker 2021-07-16 17:16:20 UTC

After analysis, the flaw is excessive allocation of memory given a specially crafted 7Z Archive. The root cause was a function causing continuous, unnecessary allocation of file objects when reading a crafted 7Z archive. Given a specially crafted archive an attacker would be able to trigger a denial of service attack against a system
