Subject: [PATCH] Fixed postgresql service network binding issue during bootup
|
||||
|
||||
During the bootup, the postgresql service requires port bind to network
|
||||
address to assign configured in /var/lib/pgsql/data/postgresql.conf but the
|
||||
service is not able to do if the network service has not yet assigned an IP
|
||||
address to the network interface.
|
||||
By using "network-online.target" parameter in
|
||||
/usr/lib/systemd/system/postgresql.service we are postponing the postgresql
|
||||
service to run until we have not got the IP address assinged.
|
||||
|
||||

Subject: [PATCH 1/1] Detect integer overflow while computing new array
|
||||
dimensions.
|
||||
|
||||
array_set_element() and related functions allow an array to be
|
||||
enlarged by assigning to subscripts outside the current array bounds.
|
||||
While these places were careful to check that the new bounds are
|
||||
allowable, they neglected to consider the risk of integer overflow
|
||||
in computing the new bounds. In edge cases, we could compute new
|
||||
bounds that are invalid but get past the subsequent checks,
|
||||
allowing bad things to happen. Memory stomps that are potentially
|
||||
exploitable for arbitrary code execution are possible, and so is
|
||||
disclosure of server memory.
|
||||
|
||||
To fix, perform the hazardous computations using overflow-detecting
|
||||
arithmetic routines, which fortunately exist in all still-supported
|
||||
branches.
|
||||
|
||||
The test cases added for this generate (after patching) errors that
|
||||
mention the value of MaxArraySize, which is platform-dependent.
|
||||
Rather than introduce multiple expected-files, use psql's VERBOSITY
|
||||
parameter to suppress the printing of the message text. v11 psql
|
||||
lacks that parameter, so omit the tests in that branch.
|
||||
|
||||
Our thanks to Pedro Gallegos for reporting this problem.
