Debian Security Advisory DSA 3565-1 (botan1.10 - security update)

Published: 2016-05-01 22:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
botan1.10 on Debian Linux

Recommendations:
For the stable distribution (jessie), these problems have been fixed in version 1.10.8-2+deb8u1. We recommend that you upgrade your botan1.10 Linux Distribution Packages.

Summary:
Several security vulnerabilities were found in botan1.10, a C++ library which provides support for many common cryptographic operations, including encryption, authentication, X.509v3 certificates and CRLs. CVE-2015-5726 The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applications reading untrusted ASN.1 data, but does not seem exploitable for code execution. CVE-2015-5727 The BER decoder would allocate a fairly arbitrary amount of memory in a length field, even if there was no chance the read request would succeed. This might cause the process to run out of memory or invoke the OOM killer. CVE-2015-7827 Use constant time PKCS #1 unpadding to avoid possible side channel attack against RSA decryption CVE-2016-2194 Infinite loop in modular square root algorithm. The ressol function implementing the Tonelli-Shanks algorithm for finding square roots could be sent into a nearly infinite loop due to a misplaced conditional check. This could occur if a composite modulus is provided, as this algorithm is only defined for primes. This function is exposed to attacker controlled input via the OS2ECP function during ECC point decompression. CVE-2016-2195 Fix Heap overflow on invalid ECC point. CVE-2016-2849 Use constant time modular inverse algorithm to avoid possible side channel attack against ECDSA.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Frequently Asked Questions

No, you can scan concurrently as many assets as you want. Please note that you must be aware of the hardware requeriments of the platform to ensure a good performance.

No, you can add as many assest as you want. It doesn't matters if you have millions of assets, we won't charge you for that.

No. The software is completely free. We have no intention to charge you to use the software, in fact - it completely goes against our beliefs and business model.

A vulnerability is defined in the ISO 27002 standard as “A weakness of an asset or group of assets that can be exploited by one or more threats” (International Organization for Standardization, 2005)

We generate revenue by providing support and other services for customers that require a subscription so they get guaranteed support and enterprise services. To use Mageni's Platform is completely free, with no limits at all.

Yes. Mageni understands that there are professionals and businesses that need commercial support so Mageni provides an active support subscription with everything needed to run Mageni's Platform reliably and securely.

No, we don't store the information of your vulnerabilities in our servers.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
