Summary
Buffer Overflow and Denial of Service vulnerabilities in Unzip were disclosed.
Unzip is used by IBM Security Virtual Server Protection for VMware. IBM
Security Virtual Server Protection for VMware has addressed the applicable
CVEs.
Vulnerability Details
CVEID: CVE-2014-8139
DESCRIPTION: UnZip is vulnerable to a heap-based buffer overflow, caused by
improper bounds checking within the CRC32 verification. A local attacker could
overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 4.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99371 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-8140
DESCRIPTION: Info-ZIP UnZip is vulnerable to a buffer overflow, caused by
improper bounds checking by the test_compr_eb() function. A local attacker
could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 4.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99372 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-8141
DESCRIPTION: Info-ZIP UnZip is vulnerable to a buffer overflow, caused by
improper bounds checking by the getZip64Data() function. A local attacker
could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 4.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/99373 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2014-9636
DESCRIPTION: Info-ZIP unzip is vulnerable to a denial of service, caused by an
out-of-bound access in extract.c. By persuading a victim to open a
specially-crafted zip file, a local attacker could exploit this vulnerability
to cause the application to crash.
CVSS Base Score: 1.9
CVSS Temporal Score: See
