Description

This security bulletin contains information about 5 vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2017-5974)

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

CVSSv4: 6.7 [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]


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

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the __zzip_get32 function in fetch.c in zziplib 0.13.62. A remote attacker can use a crafted ZIP file. to trigger 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) Heap-based buffer overflow (CVE-ID: CVE-2017-5975)

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

CVSSv4: 6.7 [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]


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

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the __zzip_get64 function in fetch.c in zziplib 0.13.62. A remote attacker can use a crafted ZIP file. to trigger 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) Heap-based buffer overflow (CVE-ID: CVE-2017-5976)

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

CVSSv4: 6.7 [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]


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

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the zzip_mem_entry_extra_block function in memdisk.c in zziplib 0.13.62. A remote attacker can use a crafted ZIP file. to trigger 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.


4) NULL pointer dereference (CVE-ID: CVE-2017-5979)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: 6.7 [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]


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 trigger denial of service conditions via a crafted ZIP file.


5) Reachable Assertion (CVE-ID: CVE-2017-5981)

CWE-ID: CWE-617 - Reachable Assertion

CVSSv4: 6.7 [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]


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

seeko.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (assertion failure and crash) via a crafted ZIP file.
