Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2024-29508)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the pdf_base_font_alloc() function. A remote attacker can pass specially crafted PDF file to the application, 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) Buffer overflow (CVE-ID: CVE-2025-27833)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing long TTF font names in pdf/pdf_fmap.c. A remote attacker can create a specially crafted document, 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.
3) Buffer overflow (CVE-ID: CVE-2025-27834)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in pdf/pdf_func.c. A remote attacker can create a specially crafted document, 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.
4) Buffer overflow (CVE-ID: CVE-2025-27835)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in psi/zbfont.c. A remote attacker can create a specially crafted document, 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.
5) Buffer overflow (CVE-ID: CVE-2025-27836)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in contrib/japanese/gdev10v.c. A remote attacker can create a specially crafted document, 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.
6) Input validation error (CVE-ID: CVE-2025-27837)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient validation of file path with invalid UTF-8 characters in base/gp_mswin.c and base/winrtsup.cpp. A remote attacker can trick the victim to open a specially crafted file and access arbitrary files on the system.
7) Input validation error (CVE-ID: CVE-2025-46646)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper validation of overlong UTF-8 encoding in decode_utf8 in base/gp_utf8.c A remote attacker can pass a specially crafted file to the application and execute arbitrary code on the system.
Note, the vulnerability exists due to incomplete fix for #VU99620 (CVE-2024-46954).
8) Input validation error (CVE-ID: CVE-2024-46954)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an unspecified error when handling untrusted input. A remote attacker can pass a specially crafted file to the application and execute arbitrary code on the system.
