Vulnerability Details
CVEID: CVE-2017-13011
Description: tcpdump is vulnerable to a buffer overflow, caused by improper bounds checking by the bittok2str_internal component. By sending an overly long string argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 7.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/131781> for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID: CVE-2017-11543
Description: tcpdump is vulnerable to a denial of service, caused by a buffer overflow in the sliplink_print function in print-sl.c. An attacker could exploit this vulnerability to cause the application to crash.
