In exif_entry_get_value of exif-entry.c, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution if a third party app used this library to process remote image data with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.1 Android-9 Android-10 Android-11 Android-8.0Android ID: A-159625731

Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is triggered in the `exif_entry_get_value` function of `exif-entry.c` in libexif; monitor for crashes or anomalous behaviour in processes loading libexif when parsing remote/untrusted image files ↗
- →No user interaction is required for exploitation; treat any network-delivered image processed by a libexif-linked application as a potential attack vector ↗
- →Attack surface is remote image data processed by third-party apps using libexif; audit all apps that call libexif to parse externally sourced images (e.g. MMS, downloads) ↗
- →Specially crafted image files (EXIF-bearing) are the delivery mechanism; inspect/sandbox image parsing pipelines and alert on malformed EXIF data causing integer overflow conditions ↗
- ·Affected Android versions are 8.0, 8.1, 9, 10, and 11; fixed versions of libexif on Debian are 0.6.22-3 and later — ensure patched library versions are deployed ↗
- ·Red Hat Enterprise Linux 5 and 6 packages are out of support scope and will not receive patches; compensating controls (e.g., restricting image processing from untrusted sources) are required on those platforms ↗
