Package : pgbouncer
Version : 1.15.0-1+deb11u1
CVE ID : CVE-2021-3935 CVE-2025-2291
Debian Bug : 1103394
PgBouncer is a lightweight connection pooler for PostgreSQL.
CVE-2021-3539
When PgBouncer is configured to use "cert" authentication, a
man-in-the-middle attacker can inject arbitrary SQL queries when a
connection is first established, despite the use of TLS certificate
verification and encryption. This flaw affects PgBouncer versions prior to
1.16.1.
CVE-2025-2291
Password can be used past expiry in PgBouncer due to auth_query not taking
into account Postgres its VALID UNTIL value, which allows an attacker to
log in with an already expired password
For Debian 11 bullseye, these problems have been fixed in version
1.15.0-1+deb11u1.
We recommend that you upgrade your pgbouncer packages.

Package : glibc
Version : 2.31-13+deb11u13
CVE ID : CVE-2025-4802
A flaw was discovered in the dynamic linking support in the GNU C
Library, the C standard library implementation used by Debian.
Privilege escalation may be possible in statically compiled setuid
binaries that call dlopen(), due to an untrusted LD_LIBRARY_PATH
environment variable vulnerability. This includes calls to dlopen()
internal to glibc itself, made after user calls to setlocale() or to NSS
functions such as getaddrinfo().
For Debian 11 bullseye, this problem has been fixed in version
2.31-13+deb11u13.
We recommend that you upgrade your glibc packages.
