CVE-2018-19625 [MEDIUM] CWE-125 wireshark: Heap-based buffer over-read in the dissection engine
wireshark: Heap-based buffer over-read in the dissection engine
In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the dissection engine could crash. This was addressed in epan/tvbuff_composite.c by preventing a heap-based buffer over-read.
An out of bounds heap read vulnerability in the dissection engine could allow Wireshark to crash when parsing a specially crafted pcap file. A remote attacker could cause a denial of service to Wireshark by injecting malicious packets into the network that are automatically processed.
Statement: This issue affects the versions of wireshark as shipped with Red Hat Enterprise Linux 5, 6, and 7.
Red Hat Enterprise Linux 5 is now in Extended Life Phase of the support and maintenance life cycle. This issue is not currently planned to be addressed in future
