Description filip ambroz 2022-03-29 06:34:45 UTC
lrzip v0.641 was discovered to contain a multiple concurrency use-after-free between the functions zpaq_decompress_buf() and clear_rulist(). This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted Irz file.

The >= doesn't make any sense to me given the fix is in 0.650?

Anyway, dupe?
