CWE
- CWE-457 - Use of Uninitialized Variable
Summary
When using the gdImageCreateFromXbm() function in the GD Graphics Library (aka LibGD) 2.2.5, as used in the PHP GD extension in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is possible to supply data that will cause the function to use the value of uninitialized variable. This may lead to disclosing contents of the stack that has been left there by previous code.

CWE
- CWE-457 - Use of Uninitialized Variable
Summary
A vulnerability in the SSL/TLS handler of Cisco Adaptive Security Appliance (ASA) Software could allow an unauthenticated, remote attacker to cause the affected device to reload unexpectedly, leading to a denial of service (DoS) condition.
The vulnerability is due to improper error handling on established SSL/TLS connections. An attacker could exploit this vulnerability by establishing an SSL/TLS connection with the affected device and then sending a malicious SSL/TLS message within that connection. A successful exploit could allow the attacker to cause the device to reload.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

CWE
- CWE-457 - Use of Uninitialized Variable
Summary
When parsing a file that is submitted to the DPDecoder service as a job, the R3D SDK will mistakenly skip over the assignment of a property containing an object referring to a UUID that was parsed from a frame within the video container. Upon destruction of the object that owns it, the uninitialized member will be dereferenced and then destroyed using the object’s virtual destructor. Due to the object property being uninitialized, this can result in dereferencing an arbitrary pointer for the object’s virtual method table, which can result in code execution under the context of the application.

Mitigation
Phase: Implementation
Strategy: Attack Surface Reduction
Description:
- Assign all variables to an initial value.
Mitigation
Phase: Build and Compilation
Strategy: Compilation or Build Hardening
Description:
- Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
Phases: Implementation, Operation
Description:
- When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.
Mitigation
Phase: Requirements
Description:
- The choice could be made to use a language that is not susceptible to these issues.
Mitigation
Phase: Architecture and Design
Description:
- Mitigating technologies such as safe string libraries and container abstractions could be introduced.
No CAPEC attack patterns related to this CWE.
