Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Use of out-of-range pointer offset (CVE-ID: CVE-2022-0554)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when reading files. A remote attacker can trick the victim to open a specially crafted file and crash the application.
2) Heap-based buffer overflow (CVE-ID: CVE-2022-0943)
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 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-2022-1154)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the utf_ptr2char() function in regexp_bt.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) Use of Out-of-range Pointer Offset (CVE-ID: CVE-2022-1420)
The vulnerability allows a remote attacker to cause a denial of service on the target application.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim to open a specially crafted file, trigger a use of out-of-range pointer offset and crash the application.
5) Heap-based buffer overflow (CVE-ID: CVE-2022-1621)
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 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.
6) Out-of-bounds read (CVE-ID: CVE-2022-1629)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a boundary condition in find_next_quote() function. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error, perform a denial of service attack, modify memory, and execute arbitrary code.
