Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2022-47024)
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 the gui_x11_create_blank_mouse(0 function in gui_x11.c. A remote attacker can perform a denial of service (DoS) attack.
2) Out-of-bounds read (CVE-ID: CVE-2023-0049)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the build_stl_str_hl() function in buffer.c. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
3) Out-of-bounds write (CVE-ID: CVE-2023-0054)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input within the do_string_sub() function in eval.c. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
4) Heap-based buffer overflow (CVE-ID: CVE-2023-0288)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ml_append_int() function in memline.c. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Heap-based buffer overflow (CVE-ID: CVE-2023-0433)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the same_leader() and utfc_ptr2len() function. A remote attacker can trick the victim to open a specially crafted file, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
