Title: Linux libc's mktemp() Vulnerability
Severity: MODERATE
Description:
Linux libc5.4.33's mktemp() function can generate only 62 unique temporary file names per process. It requires that six X's be used in the template but only one of them is really used. The rest are the process id.
This can use used as a denial of service by creating all possible temporary files a process could use before it gets to open them and possibly in symbolic link attacks by having prior knowledge of the files the process will attempt to open.
Affected Products:
- GNU glibc 2.0.0
- Linux libc 5.4.33
