Subject: [PATCH 71/72] Ticket #48192 - Individual abandoned simple paged
|
|
|
df9752 |
results request has no chance to be cleaned up
|
|
|
df9752 |
|
|
|

Description: Checking the cookie value passed by the client was not
|
|
|
df9752 |
sufficient. The negative value check was missing, which lead to
|
|
|
df9752 |
the simple paged results array out of bounds. Plus, a minor memory
|
|
|
df9752 |
leak was fixed. Thanks to Thierry Bordaz for his reviews!
