According to the versions of the freetype package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :
FreeType commit 1e2eb65048f75c64b68708efed6ce904c31f3b2f was discovered to contain a heap buffer overflow via the function sfnt_init_face. (CVE-2022-27404)
FreeType commit 53dfdcd8198d2b3201a23c4bad9190519ba918db was discovered to contain a segmentation violation via the function FNT_Size_Request. (CVE-2022-27405)
FreeType commit 22a0cccb4d9d002f33c1ba7a4b36812c7d4f46b5 was discovered to contain a segmentation violation via the function FT_Request_Size. (CVE-2022-27406)
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.
