Subject: Check for end of string in PatternMatch (CVE-2017-13720)
|
||||
|
||||
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.

Subject: pcfGetProperties: Check string boundaries (CVE-2017-13722)
|
||||
|
||||
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.
