The first two vulnerabilities are memory leaks when reading past valid memory. The last vulnerability is the possibility for an unprivileged X client to read privileged files through symlinks CVE-2017-13720 CVE-2017-13722 CVE-2017-16611 Modified: head/security/vuxml/vuln.xml Modified: head/security/vuxml/vuln.xml ============================================================================== --- head/security/vuxml/vuln.xml Sun Dec 17 16:46:05 2017 (r456559) +++ head/security/vuxml/vuln.xml Sun Dec 17 18:50:00 2017 (r456560) @@ -58,6 +58,79 @@ Notes: * Do not forget port variants (linux-f10-libxml2, libxml2, etc.) --> + + libXfont -- permission bypass when opening files through symlinks + + + libXfont + 1.5.4 + + + libXfont2 + 2.0.3 + + + + +

the freedesktop.org project reports:

+
A non-privileged X client can instruct X server running under root + to open any file by creating own directory with "fonts.dir", + "fonts.alias" or any font file being a symbolic link to any other + file in the system. X server will then open it. This can be issue + with special files such as /dev/watchdog.

The freedesktop.org project reports:

+
If a pattern contains '?' character, any character in the string + is skipped, even if it is '\0'. The rest of the matching then reads + invalid memory.
+

+
Without the checks a malformed PCF file can cause the library to + make atom from random heap memory that was behind the `strings` + buffer. This may crash the process or leak information.
