CVE-2020-13397 CVE-2020-13398

Several vulnerabilites have been reported against FreeRDP, an Open Source
server and client implementation of the Microsoft RDP protocol.

CVE-2014-0791

An integer overflow in the license_read_scope_list function in
libfreerdp/core/license.c in FreeRDP allowed remote RDP
servers to cause a denial of service (application crash) or possibly
have unspecified other impact via a large ScopeCount value in a Scope
List in a Server License Request packet.

CVE-2020-11042

In FreeRDP there was an out-of-bounds read in update_read_icon_info.
It allowed reading an attacker-defined amount of client memory (32bit
unsigned -> 4GB) to an intermediate buffer. This could have been used
to crash the client or store information for later retrieval.

CVE-2020-11045

In FreeRDP there was an out-of-bound read in in
update_read_bitmap_data that allowed client memory to be read to an
image buffer. The result displayed on screen as colour.

CVE-2020-11046

In FreeRDP there was a stream out-of-bounds seek in
update_read_synchronize that could have lead to a later out-of-bounds
read.

CVE-2020-11048

In FreeRDP there was an out-of-bounds read. It only allowed to abort
a session. No data extraction was possible.

CVE-2020-11058

In FreeRDP, a stream out-of-bounds seek in
rdp_read_font_capability_set could have lead to a later out-of-bounds
read. As a result, a manipulated client or server might have forced a
disconnect due to an invalid data read.

CVE-2020-11521

libfreerdp/codec/planar.c in FreeRDP had an Out-of-bounds Write.

CVE-2020-11522

libfreerdp/gdi/gdi.c in FreeRDP had an Out-of-bounds Read.

CVE-2020-11523

libfreerdp/gdi/region.c in FreeRDP had an Integer Overflow.

CVE-2020-11525

libfreerdp/cache/bitmap.c in FreeRDP had an Out of bounds read.

CVE-2020-11526

libfreerdp/core/update.c in FreeRDP had an Out-of-bounds Read.

CVE-2020-13396

An out-of-bounds (OOB) read vulnerability has been detected in
ntlm_read_ChallengeMessage in
winpr/libwinpr/sspi/NTLM/ntlm_message.c.

CVE-2020-13397

An out-of-bounds (OOB) read vulnerability has been detected in
security_fips_decrypt in libfreerdp/core/security.c due to an
uninitialized value.

CVE-2020-13398

An out-of-bounds (OOB) write vulnerability has been detected in
crypto_rsa_common in libfreerdp/crypto/crypto.c.

For Debian 9 stretch, these problems have been fixed in version
1.1.0~git20140921.1.440916e+dfsg1-13+deb9u4.
