Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2022-3491)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the skipwhite() function in charset.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.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-3520)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the inc() function in misc2.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.
3) Use-after-free (CVE-ID: CVE-2022-3591)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the bt_quickfix() function in buffer.c. A remote attacker can trick the victim to open a specially crafted file, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Heap-based buffer overflow (CVE-ID: CVE-2022-4141)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim to execute the CTRL-W gf in the expression used in the RHS of the substitute command, 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) Use-after-free (CVE-ID: CVE-2022-4292)
The vulnerability allows a remote attacker to compromise vulnerable system.
The
vulnerability exists due to a use-after-free error within the did_set_spelllang() funtion in spell.c. A remote attacker can trick the
victim to open a specially crafted file, trigger a use-after-free error
and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) Incorrect Comparison (CVE-ID: CVE-2022-4293)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a floating point exception within the num_divide() function in eval.c. A remote attacker can trick the victim to open a specially crafted file and crash the application.
