Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2017-5974)
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)
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)
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-2017-5977)
The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.
The zzip_mem_entry_extra_block function in memdisk.c in zziplib 0.13.62 allows remote attackers to cause a denial of service (invalid memory read and crash) via a crafted ZIP file.
5) Out-of-bounds read (CVE-ID: CVE-2017-5978)
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.
6) NULL pointer dereference (CVE-ID: CVE-2017-5979)
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) NULL pointer dereference (CVE-ID: CVE-2017-5980)
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.
8) Reachable Assertion (CVE-ID: CVE-2017-5981)
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.
9) Memory corruption (CVE-ID: CVE-2018-7726)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the __zzip_parse_root_directory function due to boundary error. A local attacker can supply a specially crafted .zip file to be processed, trigger a bus error and cause the service to crash.
10) Memory corruption (CVE-ID: CVE-2018-7727)
The vulnerability allows a local attacker to cause DoS condition on the target system.The weakness exists in the zzip_mem_disk_new function due to boundary error. A local attacker can send a specially crafted input, trigger memory leaks and cause the service to crash.
11) Memory corruption (CVE-ID: CVE-2018-6541)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists in __zzip_fetch_disk_trailer in zzip/zip.c due to bus error caused by loading of a misaligned address when handling disk64_trailer local entries. A remote attacker can submit a specially crafted zip file, trigger memory corruption and cause the service to crash.
