Several XMPP server implementations that support application-layer compression (XEP-0138) suffer from an uncontrolled resource consumption vulnerability (CWE-400). This vulnerability can be remotely exploited by attackers to mount Denial-of-Service attacks by sending highly-compressed XML elements over XMPP streams.
XMPP stream compression is a desirable feature that reduces the amount of data transferred between the protocol principals. In XMPP, compression can be negotiated at the TLS layer (as described in RFC 6120) or at the application layer (as described in XEP-0138). The vulnerability that has been discovered applies specifically to application-layer compression; such compression is negotiated between an XMPP client and server (or two servers) as follows:
The following table provides information about existing XMPP server implementations. To the best of our knowledge it is accurate and complete, but server administrators are advised to check with the developers of their preferred server software to verify the information provided here.
Justin Richards saw what he thought was a flock of birds shoot up in the sky the day his cousin, Darrell Richards was fatally injured working at the American Iron & Metal scrapyard in west Saint John.
These large cylinders are used in paper production. They weigh about 54,000 pounds, and the cotton material around them is held under 2,600 tonnes of pressure, said Michel Cyr, manager of investigations for WorkSafeNB.
Richards, 60, was sitting on the calender roll when he cut into it with a circular saw, said Cyr. The sudden release of energy severed his femoral artery and caused severe blood loss. He died in the hospital about 12 hours later.
Cyr played a short security video of the incident for the inquest, being held at the Saint John courthouse. It shows a distant silhouette of Richards working alone and then numerous pieces of blue material flying several feet into the air before being widely dispersed across the job site.
Richards had already cut the length of the calender roll but the material failed to release, so he asked Justin to use a piece of machinery to pick up the calender roll and drop it on the ground six times to see if it would break free, he said.
"Before I can release the cloth rolls, can you please email back the process that you will use to safely dismantle them? As we have discussed, these are highly compressed and can dangerously release like a compressed spring letting loose if not dismantled properly," Dave Falk, director of fixed asset management with ND, wrote on April 13, 2022.
Although AIM's Maine employees had more than 20 years of experience decommissioning calender rolls, the regional manager didn't know the hazards and shipped them to Saint John because he didn't have the manpower to deal with them, he said.
The inquest resumes Tuesday morning. Although the Department of Justice and Public Safety said it's scheduled to last all week, deputy chief coroner Michael Johnston told the courtroom he expects it to take three days
In February, a provincial court judge ordered American Iron & Metal to pay $107,000 to establish a workplace safety-focused scholarship at the New Brunswick Community College in the name of Richards, after the company changed its plea to guilty on one of four charges under the Occupational Health and Safety Act.
The company admitted to failing to take every reasonable precaution to ensure the health and safety of any person having access or using that place of employment by failing to provide information on the hazards of a calender roll to Richards.
Made from gypsum with highly compressed recycled paper fibre, Rigidur H 15mm has excellent mechanical strength for reinforcing loadbearing off-site manufactured panels. It's also widely used in schools, hospitals, prisons and commercial settings to protect busy areas that are prone to damage.

I am a long-time trial lawyer with a penchant for complex civil litigation. The cases I like the most are those that introduce me to new industries or fields of endeavor and that put a premium on preparation and efficiency. To litigate these cases requires an in-depth personal knowledge of all the facts, the witnesses and the law. It keeps the mind and spirit wonderfully engaged.
In recent years, I was involved in a very protracted proceeding opposing a project to transfer huge amounts of water from northern Nevada to Las Vegas. In 1989 the predecessor to the Southern Nevada Water District tried to tie up all of the unappropriated groundwater in northern Nevada for the benefit of Las Vegas. Ultimately, this led to a plan to extract massive amounts of water and pipe it hundreds of miles to Clark County, Nevada, at a projected cost of $15 billion.
The Cleveland Ranch, which was a part of the Church of Jesus Christ of Latter Day Saints, sat atop the principle aquifer imperiled by the plan. I was retained to oppose the plan. The State Engineer had already approved the plan but those proceedings were reopened. A six-week hearing before the State Engineer was followed by judicial review at the district court and proceedings in the Nevada Supreme Court resulting in a remand to the State Engineer. After another round of hearings and judicial review, our client prevailed and SNWA abandoned the program.
I represented the federal receiver of failed financial institutions in litigation over large fraudulent investment packages foisted upon financial institutions that probably should have known better. One such case turned into a five and one-half month jury trial.
I handled serious disputes among second generation siblings over the fate and direction of very substantial family businesses and fortunes. In each case, the first generation had created business empires of great value. Unfortunately, they each passed away without a structure that would prevent irreconcilable conflicts among the next generation.
Boxing often generates intense litigation in a highly compressed timeline with a big emphasis on injunctive relief. Las Vegas has always been a popular venue for big fights. This has given me opportunities to represent some of the best-known boxing promoters and boxers.
Disputes among real estate developers are not uncommon. That led to my representing some major national development companies in extensive litigation over ownership of property and the failure of joint venture projects.
I defended a manufacturer of medical implant devices. In one case, a whole knee replacement patient had a left knee joint incorrectly inserted into his right knee. The subsequent corrective surgeries led to further injuries and very significant damage claims. In another case, an orthotic device was prescribed with possibly insufficient instruction and ultimately caused significant injury to a patient.
There was a time when mold was the subject of a lot of fears and lawsuits. The molds themselves are commonplace in our environment, but there was a concern that any concentration of molds in an enclosed environment could cause significant health issues. In time, the evolving science undercut the more extreme claims. I successfully defended substantial wrongful death and personal injury claims arising from the exposure of ministers to mold in their church.
I conducted an arbitration that resulted in an award, and then a judgment, of over $28,000,000 to my construction company client against a subsidiary of the Diocese of Las Vegas, the owner of the Bishop Gorman High School facility which my client built. After some protracted bankruptcy proceedings, my client was able to get paid.
On October 7, 2021, Sapa, an international manufacturer of highly sophisticated aluminum alloys, entered into a multi-million-dollar settlement with the U.S. government. For years, a division of Sapa had been deliberately falsifying test results for specialized alloys sold to governments and private companies. Defective aluminum supplied by Sapa caused the loss of two NASA satellites at a cost of over $700,000,000. A Nevada company was also harmed by substandard aluminum alloy produced by Sapa. I handled the litigation for that company and the subsequent substantial settlement.
For many years, I was Chairman of the Southern Nevada Panel of the State Bar Disciplinary Committee. I am now a member of the State Bar Ethics Committee and occasionally write and lecture on trial techniques, legal ethics, and the avoidance of malpractice claims. Once in a while, I act as an expert witness on ethical and malpractice issues.
I am a Fellow in the American College of Trial Lawyers, a professional association of lawyers and judges particularly skilled in trial practice. Membership in the American College of Trial Lawyers is by invitation only and is limited to not more than one percent of the lawyers licensed to practice in a state.
For a number of years I have been recognized by Chambers & Partners for expertise in a broad range of complex commercial disputes. I am listed in Nevada Super Lawyers for business litigation and have an AV rating from Martindale Hubble.
I held a United States Coast Guard license to operate commercial vessels up to 100 tons. As many boat owners who do their own maintenance must be, I am a certified scuba diver. In the rest of my spare time, I try to convert various hardwoods into furniture in my woodshop. Even though I have been doing this for decades, I still have all my digits (but a few scars). My wife and I enjoy subjecting houses to extensive remodeling. Swinging a sledgehammer releases a lot of tension.
I was born in 1945 in Brooklyn, New York. In 1967 I married the former Charlotte Werth. Together we produced two sons, both of whom became lawyers. Each son was responsible for a fine granddaughter. Symmetry seems to rule.
