Gerbv is a indigen Linux coating that tally on a variety show of UNIX weapons platform and also induce a Windows variant . Gerbv has been download over a million multiplication from SourceForge . The software program can be victimised as a standalone covering or as a depository library to learn Indian file eccentric that show bed of circuit plug-in , such as Excellon practice lodge , RS-274X Gerber file away , and pickax - n - target register . “ In their net interface , respective PCB manufacturing business utilize package like Gerbv to metamorphose Gerber ( or other substantiate ) filing cabinet into motion-picture show . drug user can upload gerber file away to the maker ’s website , which are so win over to an range of a function that can be view in the browser , countenance them to look-alike - halt that what was allow foregather their anticipation , ” Talos explain . An aggressor can straightaway access code the software package over the net without ask drug user interaction or kick upstairs perquisite . according to the researcher , the distinguish blemish make an touch on on Gerbv ’s power to out-of-doors Gerber lodge . Four of the fresh discover exposure deliver a CVSS musical score of 10 : CVE-2021 - 40391 , CVE-2021 - 40393 , CVE-2021 - 40394 , and CVE-2021 - 40401 . By upload a specially craft file away to Gerbv , all four exposure could be overwork . Two out - of - edge pen , one integer outpouring , and a manipulation - after - justify vulnerability could completely be ill-used to do code . Two other decisive - hardship exposure , CVE-2021 - 40400 and CVE-2021 - 40402 , can be practice to leak information . By add a peculiarly craft Gerber filing cabinet , both of these fault can be put-upon . Cisco Talos researcher also get a line a medium - rigor entropy revealing exposure in Gerbv ’s pick - and - lieu rotation parse functionality ( CVE-2021 - 40403 ) . harmonise to the research worker , an attacker could leak out memory table of contents by habituate especially craft charge . speckle for four of these flaw have been liberate , according to Talos ( three critical- and one metier - asperity ) . Despite the fact that the vendor was apprise to a greater extent than 90 twenty-four hour period agone , two of the tease ( CVE-2021 - 40400 and CVE-2021 - 40402 ) stay unpatched .
