Nextcloud: Application Data Hiding via Invalid `iconName` Causing Frontend Crash in Nextcloud Tables

A vulnerability was discovered in the Tables application where invalid icon names were accepted by the backend without validation. When an invalid icon name was submitted, the frontend would crash during rendering, causing application data to become inaccessible to users. The issue stemmed from...

A Novel APVD Steganography Technique Incorporating Pseudorandom Pixel Selection for Robust Image Security

Steganography is the process of embedding secret information discreetly within a carrier, ensuring secure exchange of confidential data. The Adaptive Pixel Value Differencing APVD steganography method, while effective, encounters certain challenges like the "unused blocks" issue. This problem can...

Joint Data Hiding and Partial Encryption of Compressive Sensed Streams

The paper proposes a method to secure the Compressive Sensing CS streams. It consists in protecting part of the measurements by a secret key and inserting the code into the rest. The secret key is generated via a cryptographically secure pseudo-random number generator CSPRNG and XORed with the...

Code injection

In QUIC in RFC 9000, the Latency Spin Bit specification section 17.4 does not strictly constrain the bit value when the feature is disabled, which might allow remote attackers to construct a covert channel with data represented as changes to the bit value. NOTE: The "Sheridan, S., Keane, A. 2015...

RFC 9000 Security Vulnerabilities

RFC 9000 is a protocol for the fast and secure transmission of data over the Internet. A security vulnerability exists in RFC 9000 that originated to allow a remote attacker to construct a covert channel using data represented as bit-value changes to hide or embed data in seemingly normal network...
