Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Multiple integer overflows in libgfortran might allow remote attackers to execute arbitrary code or cause a denial of service (Fortran application crash) via vectors related to array allocation.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-190

An arithmetic operation produces a value too large for its type and wraps around to an unexpected — often tiny or negative — number. That miscalculated value then drives a memory allocation or a bounds check, opening the door to corruption. The fix is checked arithmetic and validating sizes before they're used.

Upgrade available Upgrade to 4.8 or later
Fixed in 4.8
Recommended fix High confidence

GCC/Libgfortran 4.8 or later

  1. Identify the current version of libgfortran installed (e.g., using 'gfortran --version' or checking the libgfortran package)
  2. Identify your Linux distribution and package manager (yum, apt, dnf, etc.)
  3. Update the package repository to ensure latest packages are available
  4. Upgrade the GCC or libgfortran package to version 4.8 or later using the appropriate package manager command (e.g., 'yum update gcc-gfortran' or 'apt-get install libgfortran4')
  5. Verify the upgraded version meets the fixed release requirement (version >= 4.8)
  6. Rebuild and recompile any Fortran applications that were linked against the vulnerable library to ensure they use the fixed libgfortran
Caveat Upgrading GCC may introduce minor behavioral changes in compiled Fortran applications; thorough testing of critical applications is recommended
