Description Jeff Kowalczyk 2022-10-04 21:16:37 UTC

Reader.Read did not set a limit on the maximum size of file headers. A maliciously crafted archive could cause Read to allocate unbounded amounts of memory, potentially causing resource exhaustion or panics. Reader.Read now limits the maximum size of header blocks to 1 MiB.

Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.

This is CVE-2022-2879 and Go issue https://go.dev/issue/54853.
