CVE-2026-1200

Description

A flaw was found in the rgaufman/live555 fork of live555. A remote attacker could exploit a segmentation fault, in the increaseBufferTo function. This vulnerability can lead to memory corruption problems and potentially other consequences.

Statement

This vulnerability is rated Moderate for Red Hat products as it affects the live555 library, which, when used in a server context, could lead to remote code execution due to a segmentation fault. Exploitation requires a service utilizing the vulnerable increaseBufferTo function to be exposed to an attacker.

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)

Confidentiality

Technical Impact: Read Memory

If the uninitialized pointer is used in a read operation, an attacker might be able to read sensitive portions of memory.

Availability

Technical Impact: DoS: Crash, Exit, or Restart

If the uninitialized pointer references a memory location that is not accessible to the product, or points to a location that is "malformed" (such as NULL) or larger than expected by a read or write operation, then a crash may occur.

Integrity,Confidentiality,Availability

Technical Impact: Execute Unauthorized Code or Commands

If the uninitialized pointer is used in a function call, or points to unexpected data in a write operation, then code execution may be possible.
