Description
This security bulletin contains information about 18 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-21608)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the resetForm method when processing PDF files. A remote attacker can trick the victim to open a specially crafted PDF file and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Out-of-bounds read (CVE-ID: CVE-2023-21614)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing embedded fonts. A remote attacker can create a specially crafted PDF 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 read (CVE-ID: CVE-2023-21613)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing embedded fonts. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
4) Security features bypass (CVE-ID: CVE-2023-21612)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to unspecified error when handling PDF files. A remote attacker can trick the victim to open a specially crafted PDF file and bypass implemented security restrictions.
5) Security features bypass (CVE-ID: CVE-2023-21611)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to unspecified error when handling PDF files. A remote attacker can trick the victim to open a specially crafted PDF file and bypass implemented security restrictions.
6) Stack-based buffer overflow (CVE-ID: CVE-2023-21610)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated attacker can trick the victim to open a specially crafted PDF file, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Out-of-bounds write (CVE-ID: CVE-2023-21609)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when handling Annotation objects. A remote attacker can create a specially crafted PDF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
8) Buffer overflow (CVE-ID: CVE-2023-21607)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing embedded fonts. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Integer overflow (CVE-ID: CVE-2023-21579)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow when processing embedded fonts. A remote attacker can trick the victim to open a specially crafted PDF file, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Out-of-bounds write (CVE-ID: CVE-2023-21606)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing embedded fonts. A remote attacker can create a specially crafted PDF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
11) Heap-based buffer overflow (CVE-ID: CVE-2023-21605)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling embedded fonts. A remote attacker can trick the victim to open a specially crafted PDF 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.
12) Stack-based buffer overflow (CVE-ID: CVE-2023-21604)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing PDF files. A remote unauthenticated attacker can trick the victim to open a specially crafted PDF file, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) NULL pointer dereference (CVE-ID: CVE-2023-21586)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trick the victim to open a specially crafted PDF file and perform a denial of service (DoS) attack.
14) Out-of-bounds read (CVE-ID: CVE-2023-21585)
