Software firms and the National Security Agency urge developers to move to memory-safe programming languages to eliminate a major source of high-severity flaws.

### Summary Unsafe extracting using `shutil.unpack_archive()` from a remotely retrieved tarball may lead to writing the extracted file to an unintended destination. ### Details Extracting files using `shutil.unpack_archive()` from a potentially malicious tarball without validating that the destination file path is within the intended destination directory can cause files outside the destination directory to be overwritten. The vulnerable code snippet is between [L153..158](https://github.com/DataDog/guarddog/blob/a1d064ceb09d39bb28deb6972bc0a278756ea91f/guarddog/scanners/package_scanner.py#L153..158). ```python response = requests.get(url, stream=True) with open(zippath, "wb") as f: f.write(response.raw.read()) shutil.unpack_archive(zippath, unzippedpath) ``` It seems that a remotely retrieved tarball which could be with the extension `.tar.gz` happens to be unpacked using `shutil.unpack_archive()` with no destination verification/limitation of the extracted files. ###...

The Cap'n Proto library and capnp Rust package are vulnerable to out-of-bounds read due to logic error handling list-of-list. If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the consumer to read out-of-bounds memory. This could trigger a process crash in the consumer, or in some cases could allow exfiltration of private in-memory data. Impact ====== - Remotely segfault a peer by sending it a malicious message, if the victim performs certain actions on a list-of-pointer type. - Possible exfiltration of memory, if the victim performs additional certain actions on a list-of-pointer type. - To be vulnerable, an application must perform a specific sequence of actions, described below. At present, **we are not aware of any vulnerable application**, but we advise updating regardless. Fixed in ======== Unfortunately, the bug is present in inlined code, therefore the fix will...

A new data wiper malware called CryWiper has been found targeting Russian government agencies, including mayor's offices and courts. "Although it disguises itself as a ransomware and extorts money from the victim for 'decrypting' data, [it] does not actually encrypt, but purposefully destroys data in the affected system," Kaspersky researchers Fedor Sinitsyn and Janis Zinchenko said in a
