zlib (1:1.2.11.dfsg-2ubuntu1.5) focal-security; urgency=medium
* SECURITY UPDATE: heap-based buffer over-read (LP: #1988548)
- debian/patches/CVE-2022-37434-1.patch: in inflate.c, add an extra
condition to check if state->head->extra_max is greater than len
before copying, and move the len assignment to be placed before the
check.
- debian/patches/CVE-2022-37434-2.patch: in the previous patch, in
inflate.c, the place of the len assignment was causing issues so it
was moved to be placed within the check.
- CVE-2022-37434
