Debian LTS Advisory DLA-2621-1 [email protected]

Package : php-pear
Version : 1:1.10.1+submodules+notgz-9+deb9u3
CVE ID : CVE-2020-36193
Debian Bug : 980428

A vulnerability was discovered in php-pear, which provides core
packages from the PHP Extension and Application Repository. Tar.php in
Archive_Tar allows write operations with Directory Traversal due to
inadequate checking of symbolic links, a related issue to
CVE-2020-28948. An attacker could escalate privileges by overwriting
files outside the extraction directory through a crafted .tar archive.

For Debian 9 stretch, this problem has been fixed in version
1:1.10.1+submodules+notgz-9+deb9u3.

We recommend that you upgrade your php-pear packages.

For the detailed security status of php-pear please refer to
its security tracker page at:
