CVE-2020-7063: Debian Linux

Medium severity, CVSS 5.3. EPSS: 1.6% chance of exploitation in the next 30 days.

In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all access) even if the original files on the filesystem were with more restrictive permissions. This may result in files having more lax permissions than intended when such archive is extracted.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only; version 10.0 only
• Opensuse Leap: version 15.1 only
• PHP PHP: from 7.2.0, up to and including 7.2.27; from 7.3.0, up to and including 7.3.14; from 7.4.0, up to and including 7.4.2
• Tenable Tenable.sc: before 5.19.0 (fixed in 5.19.0)
