Alpine: multiple freerdp packages: security update to 3.29.0-r0
high Tenable Self-Hosted Container Security Plugin ID 444730
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP
clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when
multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to
allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in
version 3.28.0. (CVE-2026-57156)
- FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, FreeRDP server
implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied
DeviceName and VirtualChannelName fields for a NUL terminator in
channels/rdpecam/server/camera_device_enumerator_main.c and then dereference once past the scan bound,
allowing a malicious RDP client to trigger a 1- to 2-byte out-of-bounds heap read. This issue is fixed in
version 3.28.0. (CVE-2026-57157)
- FreeRDP is a free implementation of the Remote Desktop Protocol. From 3.21.0 before 3.28.0, FreeRDP
clients using the GFX pipeline contain an incomplete fix for CVE-2026-23530 in
planar_decompress_plane_rle_only in libfreerdp/codec/planar.c, allowing a malicious RDP server to send a
truncated RDPGFX_CMDID_WIRETOSURFACE_1 planar payload that reads one byte past the input buffer. This
issue is fixed in version 3.28.0. (CVE-2026-57158)
Solution
Update the freerdp library and its related packages to version 3.29.0-r0 or later.See Also
