Synopsis

The remote Debian host is missing a security update.

Description

Vulnerabilities have been discovered in nss, the Mozilla Network Security Service library.

CVE-2019-11719: Out-of-bounds read when importing curve25519 private key

When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure.

CVE-2019-11729: Empty or malformed p256-ECDH public keys may trigger a segmentation fault

Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used.

For Debian 8 'Jessie', these problems have been fixed in version 2:3.26-1+debu8u5.

We recommend that you upgrade your nss packages.

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.

Solution

Upgrade the affected packages.
