Package : php5 Version : 5.6.40+dfsg-0+deb8u12 CVE ID : CVE-2019-11048 It has been discovered, that a vulnerability in php5, a server-side, HTML-embedded scripting language, could lead to exhausted disk space on the server. When using overly long filenames or field names, a memory limit could be hit which results in stopping the upload but not cleaning up behind. Further the embedded version of "file" is vulnerable to CVE-2019-18218. As it can not be exploited the same in php5 as in file, this issue is not handled as an own CVE but just as a bug, that has been fixed here (restrict the number of CDF_VECTOR elements to prevent a heap-based buffer overflow (4-byte out-of-bounds write)). For Debian 8 "Jessie", this problem has been fixed in version 5.6.40+dfsg-0+deb8u12. We recommend that you upgrade your php5 packages.
