Debian DLA-3316-1 : postgresql-11 - LTS security update
low Nessus Plugin ID 171363
Language:
Synopsis
The remote Debian host is missing a security-related update.Description
The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3316 advisory.- PostgreSQL Project reports: A modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. When a libpq client application has a Kerberos credential cache and doesn't explicitly disable option gssencmode, a server can cause libpq to over-read and report an error message containing uninitialized bytes from and following its receive buffer. If libpq's caller somehow makes that message accessible to the attacker, this achieves a disclosure of the over-read bytes. We have not confirmed or ruled out viability of attacks that arrange for a crash or for presence of notable, confidential information in disclosed bytes. (CVE-2022-41862)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Upgrade the postgresql-11 packages.For Debian 10 buster, this problem has been fixed in version 11.19-0+deb10u1.
