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 stack-based buffer overflows in AFFLIB before 2.2.6 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via (1) a long LastModified value in an S3 XML response in lib/s3.cpp; (2) a long (a) path or (b) bucket in an S3 URL in lib/vnode_s3.cpp; or (3) a long (c) EFW, (d) AFD, or (c) aimage file path. NOTE: the aimage vector (3c) has since been recalled from the researcher's original advisory, since the code is not called in any version of AFFLIB.

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.

Recommended fix Moderate confidence

AFFLIB version 2.2.6 or later

  1. 1. Identify the current AFFLIB version installed on the system using 'affinfo --version' or checking package management tools
  2. 2. Obtain AFFLIB version 2.2.6 or later from the official source (https://github.com/synthetic-sys/AFFLIBv3 or archive repository)
  3. 3. If using source compilation: download the source tarball, extract it, run './configure', then 'make', then 'make install'
  4. 4. If using a package manager (apt/yum/dpkg): install the updated package for version 2.2.6 or later if available from trusted repositories
  5. 5. Replace all existing AFFLIB binaries and libraries (/usr/local/lib/*afflib* and /usr/local/bin/*aff*) with the newly built/installed versions
  6. 6. Verify the upgrade by running 'affinfo --version' and confirming it reports 2.2.6 or higher
  7. 7. Rebuild any dependent applications that link against AFFLIB to ensure they use the updated libraries
