GHSA-QG3J-XJ32-H7FH
Vulnerability from github – Published: 2022-02-19 00:01 – Updated: 2022-03-01 00:01This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.0.80. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of TIF images. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15411.

GHSA-R53H-JV2G-VPX6
Vulnerability from github – Published: 2024-02-22 19:34 – Updated: 2024-07-08 12:59A Helm contributor discovered uninitialized variable vulnerability when Helm parses index and plugin yaml files missing expected content.
Impact
When either an index.yaml file or a plugins plugin.yaml file were missing all metadata a panic would occur in Helm.
In the Helm SDK this is found when using the LoadIndexFile or DownloadIndexFile functions in the repo package or the LoadDir function in the plugin package. For the Helm client this impacts functions around adding a repository and all Helm functions if a malicious plugin is added as Helm inspects all known plugins on each invocation.
Patches
This issue has been resolved in Helm v3.14.2.
Workarounds
If a malicious plugin has been added which is causing all Helm client commands to panic, the malicious plugin can be manually removed from the filesystem.
If using Helm SDK versions prior to 3.14.2, calls to affected functions can use recover to catch the panic.
For more information
Helm's security policy is spelled out in detail in our SECURITY document.

Mitigation MIT-57
Strategy: Attack Surface Reduction
Ensure that critical variables are initialized before first use [REF-1485].
Mitigation
Strategy: Compilation or Build Hardening
Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
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
Strategy: Language Selection
Choose a language that is not susceptible to these issues.
Mitigation
Mitigating technologies such as safe string libraries and container abstractions could be introduced.
No CAPEC attack patterns related to this CWE.
