Several vulnerabilities have been discovered in the PostgreSQL
Jingzhou Fu discovered a memory disclosure flaw in aggregate
Pedro Gallegos reported integer overflow flaws resulting in buffer
overflows in the array modification functions.
Hemanth Sandrana and Mahendrakar Srinivasarao reported that the
pg_cancel_backend role can signal certain superuser processes,
potentially resulting in denial of service.
Micah Gate, Valerie Woolard, Tim Carey-Smith, and Christoph Berg
reported that an extension script using @substitutions@ within
quoting may allow to perform an SQL injection for an attacker having
database-level CREATE privileges.
For the oldstable distribution (bullseye), these problems have been
fixed in version 13.13-0+deb11u1.
We recommend that you upgrade your postgresql-13 packages.
