Debian Security Advisory
DLA-2465-1 php-pear -- LTS security update
- Date Reported:
- 23 Nov 2020
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2020-28948, CVE-2020-28949.
- More information:
It was discovered that there was a filename sanitisation issue in php-pear, a distribution system for reusable PHP components.
Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked.
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.
For Debian 9
Stretch, these problems have been fixed in version 1:1.10.1+submodules+notgz-9+deb9u2.
We recommend that you upgrade your php-pear packages.
