Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2024-32039)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in clear_decompress_residual_data. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

2) Integer underflow (CVE-ID: CVE-2024-32040)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer underflow in nsc_rle_decode. A remote attacker can send a specially crafted request to the affected application, trigger integer underflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

3) Out-of-bounds read (CVE-ID: CVE-2024-32041)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in zgfx_decompress_segment. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.

4) Out-of-bounds read (CVE-ID: CVE-2024-32458)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in planar_skip_plane_rle. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.

5) Out-of-bounds read (CVE-ID: CVE-2024-32460)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in interleaved_decompress. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.

6) NULL pointer dereference (CVE-ID: CVE-2024-32661)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in rdp_write_logon_info_v1. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

7) Out-of-bounds read (CVE-ID: CVE-2024-32658)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in ExtractRunLengthRegular. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.
