Package : nss Version : 2:3.61-1+deb11u4 CVE ID : CVE-2024-0743 CVE-2024-6602 CVE-2024-6609

nss - Network Security Service libraries

This is a set of libraries designed to support cross-platform development of security-enabled client and server applications. It can support SSLv2 and v4, TLS, PKCS #5, #7, #11, #12, S/MIME, X.509 v3 certificates and other security standards.

Among other utilities, this package includes:
* certutil: manages certificate and key databases (cert7.db and key3.db)
* modutil: manages the database of PKCS11 modules (secmod.db)
* pk12util: imports/exports keys and certificates between the cert/key databases and files in PKCS12 format.
* shlibsign: creates .chk files for use in FIPS mode.
* signtool: creates digitally-signed jar archives containing files and/or code.
* ssltap: proxy requests for an SSL server and display the contents of the messages exchanged between the client and server.

CVE-2024-0743

An unchecked return value in TLS handshake code could have caused a potentially exploitable crash.

CVE-2024-6602

A mismatch between allocator and deallocator could have lead to memory corruption.

CVE-2024-6609

When almost out-of-memory an elliptic curve key which was never allocated could have been freed again.

For Debian 11 bullseye, these problems have been fixed in version 2:3.61-1+deb11u4.

We recommend that you upgrade your nss packages.
