Pointer corruption in Unified Shader Compiler in Intel Graphics Drivers before 10.18.x.5056 (aka 15.33.x.5056), 10.18.x.5057 (aka 15.36.x.5057) and 20.19.x.5058 (aka 15.40.x.5058) may allow an unauthenticated remote user to potentially execute arbitrary WebGL code via local access.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | The remote host is running a version of macOS or Mac OS X that is 10.15.x prior to 10.15.1, 10.14.x prior to 10.14.6 security update 2019-001, 10.13.x prior to 10.13.6 security update 2019-006. It is, therefore, affected by multiple vulnerabilities : - An out-of-bounds read error exists in the accounts component due to improper input validation. A remote attacker can exploit this, to disclose memory contents. (CVE-2019-8787) - A security bypass vulnerability exists in the App Store component due to an improper state management implementation. A local attacker can exploit this, to login to the account of a previously logged in user without valid credentials. (CVE-2019-8803) - An out-of-bounds read error exists in the IOGraphics component due to improper bounds checking. A local attacker can exploit this, to cause unexpected system termination or to read kernel memory. (CVE-2019-8759) Note that Nessus has not tested for this issue but has instead relied only on the operating system |
