CVE-2020-0198· NVD / CVE Program· CNA google_android

In exif_data_load_data_content of exif-data.c, there is a possible UBSAN abort due to an integer overflow.

Noroxi assessment

Priority: Monitor (action score 31/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.2% (FIRST EPSS); higher than 91% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: libexif (Debian:12) 0.6.22-2; libexif (Debian:8) 0.6.21-2+deb8u4; libexif (openSUSE:Leap 15.3) 0.6.22-150000.5.9.1.

Low priority for now. Upgrade to libexif (Debian:12) 0.6.22-2; libexif (Debian:8) 0.6.21-2+deb8u4; libexif (openSUSE:Leap 15.3) 0.6.22-150000.5.9.1 or later.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
