Description

This security bulletin contains information about 3 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2024-26256)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in libarchive. A remote attacker can trick the victim to open a specially crafted archive, 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) Out-of-bounds write (CVE-ID: CVE-2024-20697)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to insufficient validation of user-supplied input in the Windows Libarchive. A remote attacker can trick a victim to open a specially crafted website or open a file and execute arbitrary code on the target system.


3) Out-of-bounds read (CVE-ID: CVE-2024-37407)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the slurp_central_directory() function in archive_read_support_format_zip.c. A remote attacker can create a specially crafted archive, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
