CVE-2026-94090
Description
A flaw was found in JusticeRage Manalyze. A remote attacker could exploit an integer underflow vulnerability within the PE parser's _parse_debug function by manipulating the misc.Length argument, which requires user interaction. This could lead to information disclosure, denial of service, and potentially other impacts.
Statement
This vulnerability is rated as Moderate because exploitation requires a user to supply a specially crafted binary to the parser, limiting the attack vector to situations where untrusted files are analyzed, and the resulting integer underflow causes bounded impact to the host process. Furthermore, Manalyze is not packaged or distributed in Red Hat enterprise products, leaving default Red Hat environments unaffected.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Instability
This weakness will generally lead to undefined behavior and therefore crashes. In the case of overflows involving loop index variables, the likelihood of infinite loops is also high.
Integrity
Technical Impact: Modify Memory
If the value in question is important to data (as opposed to flow), simple data corruption has occurred. Also, if the wrap around results in other conditions such as buffer overflows, further memory corruption may occur.
Confidentiality,Availability,Access Control
Technical Impact: Execute Unauthorized Code or Commands; Bypass Protection Mechanism
This weakness can sometimes trigger buffer overflows which can be used to execute arbitrary code. This is usually outside the scope of a program's implicit security policy.
