Subject: [PATCH] plug-ins: Fix PSP vulnerability (ZDI-CAN-22097)
|
|
|
|
Resolves #10071.
|
|
|
|
When reading RLE compressed data, a buffer was allocated to 127 bytes.
|
|
However, it can potentially be used to read 128 bytes, leading to a
|
|
off-by-one vulnerability. This patch allocates 128 bytes to the buffer
|
|
to prevent this from occurring.
