CVE-2026-44942
Description
A flaw was found in libzypp. This path traversal vulnerability, present in the handling of the "path" component within .repo files, could allow attackers to write content to directories outside of the intended zypp cache. This unauthorized writing of data can lead to a Denial of Service (DoS) by filling up disk space on the system.
Statement
This Moderate impact vulnerability in libzypp allows a path traversal when processing specially crafted .repo files. An attacker could exploit this flaw to write arbitrary content outside the intended zypp cache, potentially leading to a denial of service by exhausting disk space. This issue affects systems that process untrusted .repo files.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity
Technical Impact: Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.
Confidentiality
Technical Impact: Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
