Fix CVE-2008-2149: buffer overflows by limiting the length of the string in sprintf
|
||
|
|
format string
|
||
|
|
Closes: #481186 (CVE-2008-2149)
|
||
|
|
Please note: The WordNet code contains several other occurences of potentially
|
||
|
|
exploitable functions like strcpy()/strcat()/... and so even if there are no
|
||
|
|
known exploits the code needs a full security audit.
