Michael Jumper reassigned GUACAMOLE-324: ---------------------------------------- Assignee: Michael Jumper > Incorrect buffer used in socket write > ------------------------------------- > > Key: GUACAMOLE-324 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-324 > Project: Guacamole > Issue Type: Bug > Components: libguac > Reporter: Michael Jumper > Assignee: Michael Jumper > Priority: Minor > > Within the file descriptor implementation of {{guac_socket}} (and possibly > elsewhere), the call to {{send()}} or {{write()}} uses the pointer which > always points to the beginning of the buffer, rather than the pointer which > is updated as chunks are written: > https://github.com/apache/incubator-guacamole-server/blob/770a2805e4936aa73f17277a7ec6a762fdcc671a/src/libguac/socket-fd.c#L92-L118 > This will result in duplicate data being written if the first write does not > succeed in writing absolutely everything, most likely resulting in invalid > protocol data and a disconnect. > Based on the fact that Guacamole works ... it seems this is rather unlikely > in practice, but it should be fixed. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
