Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2024-29509)
The vulnerability allows a remote attacker to crash the application.
The vulnerability exists due to a boundary error when parsing passwords, when PDFPassword (e.g., for runpdf) has a 00 byte in the middle. A remote attacker can trick the victim to pass a specially crafted password to the application, trigger a heap-based buffer overflow and crash it.
2) 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.
3) Stack-based buffer overflow (CVE-ID: CVE-2024-29507)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing the CIDFSubstPath and CIDFSubstFont parameters. A remote attacker can 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.
4) Stack-based buffer overflow (CVE-ID: CVE-2024-29506)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the pdfi_apply_filter() function via a long PDF filter name. A remote attacker can pass a specially crafted file to the application, 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.
