Android July 2019 Security Update Patches 33 New Vulnerabilities

Jul 2, 2019

Google has started rolling out this month’s security updates
for its mobile operating system platform to address a total of 33
new security vulnerabilities affecting Android devices, 9 of which
have been rated critical in severity.

The vulnerabilities affect various Android components, including
the Android operating system, framework, library, media framework,
as well as Qualcomm components, including closed-source
components.

Three of the critical vulnerabilities patched this month reside in
Android’s Media framework, the most severe of which could allow a
remote attacker to execute arbitrary code on a targeted device,
within the context of a privileged process, by convincing users
into opening a specially crafted malicious file.

“The severity assessment is based on the effect that exploiting the
vulnerability would possibly have on an affected device, assuming
the platform and service mitigations are turned off for development
purposes or if successfully bypassed,” the company says ^[1].

Out of the remaining seven critical vulnerabilities, one affects
Android Library, one affects the System, two resides in Qualcomm
components (one in DSP_Services and one in Kernel), and three
resides in Qualcomm closed-source components.

Besides this, a high-severity flaw (CVE-2019-2104) in the
Android Framework could allow an installed malicious app to bypass
user interaction requirements in an attempt to gain access to
additional permissions.

Six high-severity vulnerabilities addressed in Qualcomm
components resides in WLAN Host (CVE-2019-2276, CVE-2019-2307),
WLAN Driver (CVE-2019-2305), HLOS (CVE-2019-2278), and Audio
(CVE-2019-2326, CVE-2019-2328).

According to the Android security advisory, none of the flaws
addressed this month were publicly disclosed or found being
exploited in the wild.

Apart from releasing patches for security vulnerabilities, the
Android Security Patch for July 2019 also includes fixes for
various issues in some of the supported version of Pixel devices.

Pixel smartphone users will get the July updates shortly, while
others will have to wait for their Android device manufacturers or
service providers to roll out the security patches for their
devices.

Users are strongly recommended to download the most recent
Android security updates as soon as they are available in order to
keep their Android devices protected against any potential
attack.

Injection. Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization. Broken Authentication. Application functions related to authentication and session management are often implemented incorrectly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users’ identities temporarily or permanently. Sensitive Data Exposure. Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser. XML External Entities (XXE). Many older or poorly configured XML processors evaluate external entity references within XML documents. External entities can be used to disclose internal files using the file URI handler, internal file shares, internal port scanning, remote code execution, and denial of service attacks. Broken Access Control. Restrictions on what authenticated users are allowed to do are often not properly enforced. Attackers can exploit these flaws to access unauthorized functionality and/or data, such as access other users’ accounts, view sensitive files, modify other users’ data, change access rights, etc. Security Misconfiguration. Security misconfiguration is the most commonly seen issue. This is commonly a result of insecure default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages containing sensitive information. Not only must all operating systems, frameworks, libraries, and applications be securely configured, but they must be patched/upgraded in a timely fashion. Cross-Site Scripting XSS. XSS flaws occur whenever an application includes untrusted data in a new web page without proper validation or escaping, or updates an existing web page with user-supplied data using a browser API that can create HTML or JavaScript. XSS allows attackers to execute scripts in the victim’s browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites. Insecure Deserialization. Insecure deserialization often leads to remote code execution. Even if deserialization flaws do not result in remote code execution, they can be used to perform attacks, including replay attacks, injection attacks, and privilege escalation attacks. Using Components with Known Vulnerabilities. Components, such as libraries, frameworks, and other software modules, run with the same privileges as the application. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications and APIs using components with known vulnerabilities may undermine application defenses and enable various attacks and impacts. Insufficient Logging & Monitoring. Insufficient logging and monitoring, coupled with missing or ineffective integration with incident response, allows attackers to further attack systems, maintain persistence, pivot to more systems, and tamper, extract, or destroy data. Most breach studies show time to detect a breach is over 200 days, typically detected by external parties rather than internal processes or monitoring.
