CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
FreeRDP versions prior to 3.5.0
FreeRDP versions prior to 2.11.6
Description
The issue is related to out-of-bounds read and integer overflow in functions such as
ncrush decompress(), zgfx decompress segment, clear decompress residual data, nsc rle decode, planar skip plane rle, and interleaved decompress. This can allow a remote attacker to execute arbitrary code. No known workarounds are available.Recommendations
For FreeRDP versions prior to 3.5.0, update to version 3.5.0 to resolve the issue.
For FreeRDP versions prior to 2.11.6, update to version 2.11.6 to resolve the issue.
As a temporary workaround, consider disabling the
ncrush decompress() function until a patch is available.
Restrict access to the vulnerable modules zgfx decompress segment, clear decompress residual data, nsc rle decode, planar skip plane rle, and interleaved decompress to minimize the risk of exploitation.Exploit
