# CL Signatures Issuer Key Correctness Proof lacks of prime strength checking A weakness in the Hyperledger AnonCreds specification that is not mitigated in the Ursa and AnonCreds implementations is that the Issuer does not publish a key correctness proof demonstrating that a generated private key is sufficient to meet the unlinkability guarantees of AnonCreds. A sufficient private key is one in which it's components `p` and `q` are safe primes, such that: - `p` and `q` are both prime numbers - `p` and `q` are not equal - `p` and `q` have the same, sufficiently large, size - For example, using two values both 1024 bits long is sufficient, whereas using one value 2040 bits long and the other 8 bits long is not. The Ursa and AnonCreds CL-Signatures implementations always generate a sufficient private key. A malicious issuer could in theory create a custom CL Signature implementation (derived from the Ursa or AnonCreds CL-Signatures implementations) that uses weakened private keys su...

### Summary A **stored cross-site scripting (XSS)** vulnerability was found in the **key_value** field of Avo v3.2.3. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the victim's browser. ### Details The value of the key_value is inserted directly into the HTML code. In the current version of Avo (possibly also older versions), the value is not properly sanitized before it is inserted into the HTML code. This vulnerability can be exploited by an attacker to inject malicious JavaScript code into the key_value field. When a victim views the page containing the malicious code, the code will be executed in their browser. In [avo/fields/common/key_value_component.html.erb]( https://github.com/avo-hq/avo/blob/main/app/components/avo/fields/common/key_value_component.html.erb#L38C21-L38C33) the value is taken in lines **38** and **49** and seems to be interpreted directly as html in lines **44** and **55**. ### PoC ![POC](https://user-images.githubuserc...

Ubuntu Security Notice 6579-2 - USN-6579-1 fixed a vulnerability in Xerces-C++. This update provides the corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 23.04 and Ubuntu 23.10. It was discovered that Xerces-C++ was not properly handling memory management operations when parsing XML data containing external DTDs, which could trigger a use-after-free error. If a user or automated system were tricked into processing a specially crafted XML document, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 6584-1 - Philipp Jeitner and Haya Shulman discovered that Libspf2 incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that Libspf2 incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

Ubuntu Security Notice 6581-1 - It was discovered that GNU binutils was not properly performing bounds checks in several functions, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service, expose sensitive information or execute arbitrary code. It was discovered that GNU binutils incorrectly handled memory management operations in several of its functions, which could lead to excessive memory consumption due to memory leaks. An attacker could possibly use these issues to cause a denial of service.
