| Doc Text: |
A heap memory leak in tslib 1.22 allows context-dependent attackers to leak the heap chunk address of the library via deleting tslib configuration file.
If the /usr/local/etc/ts.conf configuration file does not exist, a use-after-free vulnerability can occur and the library heap memory address may be leaked.
