Package        : zlib
CVE ID         : CVE-2022-37434
Debian Bug     : 1016710

Evgeny Legerov reported a heap-based buffer overflow vulnerability in
the inflate operation in zlib, which could result in denial of service
or potentially the execution of arbitrary code if specially crafted
input is processed.

For the stable distribution (bullseye), this problem has been fixed in
version 1:1.2.11.dfsg-2+deb11u2.

We recommend that you upgrade your zlib packages.

For the detailed security status of zlib please refer to its security
tracker page at:
