Detailsinfo

A vulnerability was found in Wireshark (Packet Analyzer Software). It has been classified as problematic. This affects an unknown code of the file wiretap/pcapng.c of the component pcapng File Parser. The manipulation with an unknown input leads to a injection vulnerability. CWE is classifying the issue as CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. This is going to have an impact on availability. The summary by CVE is:

In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the pcapng file parser could crash. This was addressed in wiretap/pcapng.c by adding a block-size check for sysdig event blocks.
