Description GLSAMaker/CVETool Bot gentoo-dev 2021-05-14 13:59:56 UTC 
CVE-2020-36326 (https://nvd.nist.gov/vuln/detail/CVE-2020-36326):
  PHPMailer 6.1.8 through 6.4.0 allows object injection through Phar
  Deserialization via addAttachment with a UNC pathname. NOTE: this is similar
  to CVE-2018-19296, but arose because 6.1.8 fixed a functionality problem in
  which UNC pathnames were always considered unreadable by PHPMailer, even in
  safe contexts. As an unintended side effect, this fix eliminated the code
  that blocked addAttachment exploitation.
