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
In pvmp3_get_main_data_size of pvmp3_get_main_data_size.cpp, there is a possible buffer overread due to a missing bounds check. This could lead to remote information disclosure of global static variables with no additional execution privileges needed. User interaction is not needed for exploitation.

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.

How this class of weakness works · CWE-120

A fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

Recommended fix High confidence

Update to Android security patch level 2018-05-01 or later (for Android 7.0, 7.1.1, 7.1.2, 8.0 devices)

  1. 1. Check current Android security patch level on the device: Settings > About Phone > Android version/security patch level
  2. 2. Verify if the device has received the May 2018 security update (2018-05-01) or later
  3. 3. If not updated, navigate to Settings > System > Software Update (or Settings > About Phone > System Update)
  4. 4. Check for updates and install any available security updates
  5. 5. Ensure the device updates to the May 2018 security patch level or newer to remediate CVE-2017-13319
  6. 6. After update, verify the security patch level reflects the May 2018 update or later in Settings > About Phone
Caveat Security updates are cumulative; applying the May 2018 patch should not introduce breaking changes but will include all prior 2018 security patches
