Description

asyncpg before 0.21.0 allows a malicious PostgreSQL server to trigger a crash or execute arbitrary code (on a database client) via a crafted server response, because of access to an uninitialized pointer in the array data decoder.

For Debian 9 stretch, this problem has been fixed in version 0.8.4-1+deb9u1.

We recommend that you upgrade your asyncpg packages.

For the detailed security status of asyncpg please refer to its security tracker page at: https://security-tracker.debian.org/tracker/asyncpg

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
