Description

This security bulletin contains information about 3 vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2017-5601)

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

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


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

An error in the lha_read_file_header_1() function (archive_read_support_format_lha.c) in libarchive 3.2.2 allows remote attackers to trigger an out-of-bounds read memory access and subsequently cause a crash via a specially crafted archive.


2) Use-after-free (CVE-ID: CVE-2021-36976)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error in copy_string. A remote attacker can cause a denial of service condition on the target system.


3) Out-of-bounds read (CVE-ID: CVE-2022-26280)

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

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


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

The vulnerability exists due to a boundary condition when processing ZIP files in zipx_lzma_alone_init. A remote attacker can create a specially crafted .zip archive, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
