Description
This security bulletin contains information about 7 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) Out-of-bounds read (CVE-ID: CVE-2017-5978)
CWE-ID: CWE-125 - Out-of-bounds read
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.
The zzip_mem_entry_new function in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted ZIP file.
5) 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.
6) NULL pointer dereference (CVE-ID: CVE-2017-5980)
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.
7) 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.
