According to the versions of the gd package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
In the GD Graphics Library (aka LibGD) through 2.2.5, there is a heap-based buffer over-read in tiffWriter in gd_tiff.c. NOTE: the vendor says ‘In my opinion this issue should not have a CVE, since the GD and GD2 formats are documented to be ‘obsolete, and should only be used for development and testing purposes.’’(CVE-2017-6363)
gdImageClone in gd.c in libgd 2.1.0-rc2 through 2.2.5 has a NULL pointer dereference allowing attackers to crash an application via a specific function call sequence. Only affects PHP when linked with an external libgd (not bundled).(CVE-2018-14553)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
