HIGH Summary
Ruby before 2.4.2, 2.3.5, and 2.2.8 is vulnerable to a malicious format string which contains a precious specifier (*) with a huge minus value. Such situation can lead to a buffer overrun, resulting in a heap memory corruption or an information disclosure from the heap.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Format String Injection An attacker includes formatting characters in a string input field on the target application. Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An attacker can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the attacker can write to the program stack.
- String Format Overflow in syslog() This attack targets the format string vulnerabilities in the syslog() function. An attacker would typically inject malicious input in the format string parameter of the syslog function. This is a common problem, and many public vulnerabilities and associated exploits have been posted.

NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3685-1.NASL description Some of these CVE were already addressed in previous USN: 3439-1, 3553-1, 3528-1. Here we address for the remain releases. It was discovered that Ruby incorrectly handled certain inputs. An attacker could use this to cause a buffer overrun. (CVE-2017-0898) It was discovered that Ruby incorrectly handled certain files. An attacker could use this to overwrite any file on the filesystem. (CVE-2017-0901) It was discovered that Ruby was vulnerable to a DNS hijacking vulnerability. An attacker could use this to possibly force the RubyGems client to download and install gems from a server that the attacker controls. (CVE-2017-0902) It was discovered that Ruby incorrectly handled certain YAML files. An attacker could use this to possibly execute arbitrary code. (CVE-2017-0903) It was discovered that Ruby incorrectly handled certain files. An attacker could use this to expose sensitive information. (CVE-2017-14064) It was discovered that Ruby incorrectly handled certain inputs. An attacker could use this to execute arbitrary code. (CVE-2017-10784) It was discovered that Ruby incorrectly handled certain network requests. An attacker could possibly use this to inject a crafted key into a HTTP response. (CVE-2017-17742) It was discovered that Ruby incorrectly handled certain files. An attacker could possibly use this to execute arbitrary code. This update is only addressed to ruby2.0. (CVE-2018-1000074) It was discovered that Ruby incorrectly handled certain network requests. An attacker could possibly use this to cause a denial of service. (CVE-2018-8777).

(CVE-2017-14064) - It was found that the decode method of the OpenSSL::ASN1 module was vulnerable to buffer underrun. An attacker could pass a specially crafted string to the application in order to crash the ruby interpreter, causing a denial of service. (CVE-2017-14033) - It was found that rubygems could use an excessive amount of CPU while parsing a sufficiently long gem summary. A specially crafted gem from a gem repository could freeze gem commands attempting to parse its summary. (CVE-2017-0900) - It was found that rubygems did not sanitize gem names during installation of a given gem. A specially crafted gem could use this flaw to install files outside of the regular directory.

An attacker with the ability to manipulate DNS responses could direct the gem command towards a different domain. (CVE-2017-0902) - A vulnerability was found where the rubygems module was vulnerable to an unsafe YAML deserialization when inspecting a gem. Applications inspecting gem files without installing them can be tricked to execute arbitrary code in the context of the ruby interpreter. (CVE-2017-0903) - It was found that WEBrick did not sanitize all its log messages. If logs were printed in a terminal, an attacker could interact with the terminal via the use of escape sequences. (CVE-2017-10784) - It was discovered that the Net::FTP module did not properly process filenames in combination with certain operations. A remote attacker could exploit this flaw to execute arbitrary commands by setting up a malicious FTP server and tricking a user or Ruby application into downloading files with specially crafted names using the Net::FTP module. (CVE-2017-17405) - A buffer underflow was found in ruby's sprintf function. An attacker, with ability to control its format string parameter, could send a specially crafted string that would disclose heap memory or crash the interpreter.
